Answer:
∠ 3 = 127°, ∠ 4 = 37°
Step-by-step explanation:
53° and ∠ 3 are adjacent angles and are supplementary, sum to 180°, so
∠ 3 + 53° = 180° ( subtract 53° from both sides )
∠ 3 = 127°
-----------------------------------------------------------
∠ 5 and 53° are corresponding angles and are congruent, so
∠ 5 = 53°
∠ 5, ∠ 4 and 90° lie on a straight line and sum to 180° , that is
53° + ∠ 4 + 90° = 180°
∠ 4 + 123° = 180° ( subtract 123° from both sides )
∠ 4 = 37°
Answer:
10. 127°
11. 37°
Step-by-step explanation:
We have two perpendicular angles and two diagonal angles.
The horizontal one, we will mark A.
The vertical one, we will mark B.
The lower diagonal, we will mark C.
The upper diagonal, we will mark D.
We can see that the diagonals are parallel.
Angle ∠ACat3* has an angle of 53°.
*There are two angles on AC. The "at3" part means that the angle is located at the mark of three.
Since line C is straight, the two angles that are split by line A will be supplementary*.
*Meaning that the angles will add up to 180°.
180 - 53 = 127
Angle ∠ACat3 has an angle of 127°.
So, for ten, 127° is your answer.
Now for eleven.
We know that A and B intersect, and make 90° angles. Let's flip this to the other side of A and B.
Angle ∠AB affects 4 and 5. This means that the angle of 4 plus the angle of 5 will be complementary*.
*Meaning that the angles will add up to 90°
Since we know that C and D are parallel, and that the bottom side is 53°, and that the angles will be complementary, we can subtract 53 from 90 to get our answer.
90 - 53 = 37
Angle ∠ACatBat4 has an angle of 37°.
So, for eleven, 37° is your answer.
Hope this helps. Have a nice day.
The diagram shows two campsites on opposite ends of a lake and two triangles formed by intersecting segments from the campsites.
Campsites F and G are on opposite sides of a lake. A survey crew made the measurements shown on the diagram. What is the distance between the two campsites? The diagram is not drawn to scale. The triangles are proportional.
Answer:
x=42.3m
Step-by-step explanation:
x/47=82.8/92
92x=3891.6= 42.3m is the distance
Given that the triangles formed are similar, the distance between the two campsites is: 42.3 m.
What are Similar Triangles?Triangles that are similar to each other always have the same shape but different sizes, and the ratio of their corresponding sides are equal (proportional).
The two triangles formed are similar triangles. Therefore:
47/FG = 82/73.8
Cross multiply
FG = (47 × 73.8)/82
FG = 42.3 m
Therefore, given that the triangles formed are similar, the distance between the two campsites is: 42.3 m.

38 is 90 percent of what
Answer:
42.22 (2 repeating)
Step-by-step explanation:
When you are given percentage problems, you deal with the percent (%), base (amount you are starting with), and the amount.
Starting with the most basic equation,
Percent * Base = Amount
In this problem, you are given the amount (38) and the percent (90)
So to find the base, you can do
Base = Amount / Percent
As always, convert the percent to a decimal by dividing by 100.
38/ 0.9 = 42.222 repeating

The point (-4, -1), is the bottom of a triangle. Which point would it map to if the triangle was translated right 5 units and reflected about the x-axis.
Answer:
Step-by-step explanation:
(x,y)→(x+5,y)
(-4,-1)→(-4+5,-1)=(1,-1)
reflection about x-axis
(x,y)→(x,-y)
(1,-1)→(1,1)
Answer:
(1, 1)
Step-by-step explanation:
If we move the point (-4, -1) to the right 5 units, then we add 5 to the x value to give us (1, -1). We reflect (1, -1) in the x-axis, so we change the y value this time multiplying it by -1. The new point that (-4, -1) would be mapped onto would be:
(1, 1).

tan A =

option 2: 9/41
option 3: 40/41
option 4: 41/40
what is the correct answer?
Answer:
option 1: [tex]\frac{40}{9}[/tex]
Step-by-step explanation:
tan = [tex]\frac{opposite}{adjacent}[/tex]
tan A = [tex]\frac{40}{9}[/tex]
Answer:
Option 3
Step-by-step explanation:
So remember the formula for sine, cosine, and tangent: it's SOH CAH TOH. SOH is sine: opposite over hypotenuse. Cosine is CAH: adjacent over hypotenuse. Lastly, the one we're using today is tangent, TOH: opposite over hypotenuse. So for tan A, you look at the opposite side of angle A, which is side BC; the length is 40. Then you look at the hypotenuse, which is side AB; the length is 41. So, you get 40/41, which is option 3 as the answer. Hope this helps!

Analyze the following situations that represent a relationship between x and y. Which situations can be modeled by the equation y = 0.23x? Select two that apply.
Answer:
I think it's A and D
Step-by-step explanation:
For option A, y would be the height or total growth, and x would be time or months and total height = 0.23 feet × 7.5 months
for option D, y would be the total amount of money spent and x would be the number of granola bars bought. total money spent = $0.23 × number of granola bars bought
Options B and C don't work because we don't know the initial values and an initial value would be represented in the equation.
In option E, 0.23 represents the total growth in 7 days, so it would be the total instead of the rate of change

the angles of a quadrilateral are x°, (x+5)°, (2x-25)° and (x+10)°
find the value of x
Given:
The angles of a quadrilateral are x°, (x+5)°, (2x-25)° and (x+10)°.
To find:
The value of x.
Solution:
We know that the sum of all interior angles of a quadrilateral is 360°. So,
[tex]x^\circ+(x+5)^\circ+(2x-25)^\circ+(x+10)^\circ=180^\circ[/tex]
[tex](5x-10)^\circ=180^\circ[/tex]
It can be written as
[tex](5x-10)=180[/tex]
[tex]5x=180+10[/tex]
[tex]5x=190[/tex]
Divide both sides by 5.
[tex]x=\dfrac{190}{5}[/tex]
[tex]x=38[/tex]
Therefore, the value of x is 38.

4th root of 16
4 = index ; 16 = radicand
2
Step-by-step explanation:
⁴√16 is pronounced as the 4th root of 16
For expressions of this sort :
The index = 4
Radicand = 16
Sqareroot (√) is a radical symbol, and the number under the radical square root Symbol is called the radicand
Hence. The 4th root of 16:
⁴√16 ; using a calculator gives 2.
We could check our resukt by taking the 4th square of 2
2 * 2 * 2 * 2 = 16

Two people paddle a canoe in a river flowing at a rate of 3 miles per hour, then they returned traveling upstream. The entire trip was 96 miles and the trip upstream took twice as long as the trip downstream. How fast did they row in still water? How many hours was the complete trip?
Answer:
72
Step-by-step explanation:
Answer:
speed in still water = 9 mph
total time = 12 hours
Step-by-step explanation:
speed = distance/time
distance = speed * time
Traveling downstream:
speed of river = 3 mph
speed of canoe in still water = v
speed of canoe going downstream = v + 3
distance = 96/2 = 48
time = t
distance = speed * time
48 = (v + 3)(t)
Traveling upstream:
speed of river = 3 mph
speed of canoe in still water = v
speed of canoe going downstream = v - 3
distance = 96/2 = 48
time = 2t
distance = speed * time
48 - d = (v - 3)(2t)
48 = (v + 3)(t)
48 = (v - 3)(2t)
vt + 3t = 48
2vt - 6t = 48
-2vt - 6t = -96
(+) 2vt - 6t = 48
------------------------
-12t = -48
t = 4
vt + 3t = 48
4v + 3(4) = 48
4v + 12 = 48
4v = 36
v = 9
speed in still water = v = 9 mph
total time = t + 2t = 3t = 3(4) = 12 hours

a) Length of a Rectangular playground is 15m and width of the playground is
12m.David wants to level the playground .How much area he has to level?
b) David will charge 3 pound for leveling of 1m square What will be the total
amount he will charge for leveling the playground.
Answer:
A. 180 m²
B. 540 pounds
Step-by-step explanation:
Area of rectangular playground = length × width
Length of a Rectangular playground = 15m
width of the playground =
12m
Area of rectangular playground = length × width
= 15m × 12m
= 180m²
B. 1m square = 3 pounds
What will be the total amount he will charge for leveling the playground.
Total cost of leveling the playground = 180 m² × 3 pounds
= 540 pounds
PLS,PLS,PLS,PLS HELP ME THIS QUESTION IS WORTH 10 POINTS. Which number sequence follows the rule add 4 starting from 2?
Answer:
Arithmetic sequence
Step-by-step explanation:
In an arithmetic sequence, the next term on the sequence is obtained by adding a certain value to the first term. This term that is added is uniform throughout the sequence. Once this term is added to the preceding term, the next term of the sequence is obtained. This term that is thus added is known as the common difference of the arithmetic sequence.
So the arithmetic sequence obtained by adding 4 starting from 2 is; 2, 6, 10, 14 .........
