What are the measures of the interior angles of the triangle?
m∠1 =
°
m∠2 =
°
m∠3 =
°
Answer:
Step-by-step explanation:
a and b are parallel lines. So, alternate interior angles are congruent.
∠2 = 64.8°
∠3 = 30.5°
Sum of all angles of triangle = 180
∠1 + ∠2 + ∠3 = 180
∠1 + 64.8 + 30.5 = 180
∠1 + 95.3 = 180
∠1 = 180 - 95.3
∠1 = 84.7°
Which situation could be represented by the expression 1.40x?
Answer:
B. the area of a rectangle with side lengths 1.40 and x
Step-by-step explanation:
To find the area of a rectangle, multiply the length by the width.
If 1.40 is the length, x is the width.
1.40×x=1.40x
So B is the correct answer.

Q. Find the Volume
3.4
5.2
7.1
Answer choices
A. 105
B. 112.5
C. 125.5
D. 110
Answer:
[tex]\boxed{\sf{125.5m^{3} }}[/tex]Step-by-step explanation:
To determine a volume, you need a volume formula.
Volume:
[tex]\Longrightarrow:\sf{V=l*w*h}[/tex]
L stands for length: 7.1W stands for width: 5.2H stands for height: 3.4Multiply these numbers from left to right.
[tex]\sf{7.1m*5.2m*3.4m=\boxed{\sf{125.5m^{3}}}[/tex]
Therefore, the correct answer is 125.5m³.I hope this helps you! Let me know if my answer is wrong or not.

Answer:
angle HMS = 62 degrees
x = 13 degrees
AT = 28
Step-by-step explanation:
angle SHM and angle HMS are both inside the triangle SMH.
We want to find the angle of HMS. We know that the sum of the angles in the triangle adds up to 180 degrees. There are two angles that we already know.
Angle SHM = 28 (given)
Angle HSM = 90 (because it is a right angle which is always 90 degrees, right angles are formed at two perpendicular lines)
Angle HMS = x (we let angle HMS be a variable as we don't know the value for it)
x + 90 + 28 = 180
x = 62 ddegrees
HMS is 62 degrees
TSA is a right angle in triangle AST because it is formed by two perpendicular lines. Right angles always equal 90 degrees.
10x - 40 = 90
10x = 130
x = 13 degrees
AT and HT are both congruent sides. We know this because the figure we are given is a kite. In a kite, we have two pairs of sides that are congruent to each other. HT is congruent to AT while HM is congruent to AM.
So,
8x - 4 = 2x + 20
Subtraact 2 x from both sides
6x - 4 = 20
Add 4 to both sides
6x = 24
Divide 6 on both sides.
x = 4
Plug x back to AT.
AT = 2(4) + 20 = 28
find the value of x
Answer:
82•5°
Step-by-step explanation:
[tex]28 + 68.5 + x = 180[/tex]
[tex]x = 180 - 97.5[/tex]
[tex]x = 82.5[/tex]
Here,
let the forth degree of the quadrilateral be y
Then,
90° +90° +68.5° + y =360° (all the interior angle of a quadrilateral is 360°)
or, 248.5+ y=360°
or, y = 360° - 248.5°
or, y= 111.5°
Again, the second angle of the triangle be a
Then,
a=111.5(vertically opposite angle)
Lastly,
29° + 111.5° + x = 180°(all the interior angle of a triangle is 180°)
or, 140.5° + x = 180°
or, x =180° - 140.5°
or, x=39.5°

125/5=25.
So, 20% to get a card with the number 3
find the circumference
Answer:
18πm
Step-by-step explanation:
The area is πr^, so to find just the radius, take the square root of 81.
This means the radius is 9, and because the formula for the circumference is 2πr, simply double it and multiply by π to get 18π.

Step-by-step explanation:
These are two similar triangles.
What does x equal?
Answer:
112
Step-by-step explanation:
So, we know that a triangle's sides must add up to have a sum of 180. If you add up your given lengths and you should get 47, not including x. Then if you look at the left side/the one without a given length and it should be identical to the 21, so you know that side is 21. So now add 21 to 47, you should get 68. Finally, you subtract 68 from 180 like this: 180-68, and it should equal 112. So you're answer is 112.

what is the perimeter of a 12 inch by 13 inch triangle
Answer:
Perimeter = 30 in
Step-by-step explanation:
Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given:
a = ab = 12 inc = 13 inSubstitute given values into the formula and solving for a:
⇒ a² + 12² = 13²
⇒ a² + 144 = 169
⇒ a² = 25
⇒ a = 5 in
Therefore, perimeter = a + b + c
= 5 in + 12 in + 13 in
= 30 in
Final Answer:
[tex]\fbox{perimeter \: of \: triangle = 30 \: in.}[/tex]
Step by Step explanation:
Data achieved from diagram:
The given triangle is a right angle triangle
Hypotenuse of triangle = 13 in.
Base of triangle = 12 in.
To find:
Perimeter of triangle = ?
Solution:
We need length of all three sides (Altitude) of triangle,
let's find out the measure of length of Altitude using Pythagoras theorem!
[tex]{Hypotenuse}^2 = {Base}^2 + {Altitude}^2 \\ {13}^{2} = {12}^{2} + {A}^{2} \\ {A}^{2} = 169 - 144 \\ {A}^{2} = 25 \\ {A} = \sqrt{25 } \\ \fbox{A = 5 \: in.}[/tex]
Now we have all three sides of triangle,
[tex]perimeter \: of \: triangle = Hyp. + Base + Alt. \\perimeter \: of \: triangle = 13 + 12 + 5 \\ \fbox{perimeter \: of \: triangle = 30 \: in.}[/tex]

Question 12 options:
y= 2x + 1
y= -x -2
y= x + 2
y= -2x + 1
Answer:
y = x+2
Step-by-step explanation:
y = mx +c
y-intercept is +2
so y = mx + 2
the slope of the line is one across one up so
y = x+2
Answer:
Step-by-step explanation:
At y-intercept, x =0
So, from the graph, y-intecept = b = 2
Equation of the line: y =mx +b
y = mx + 2
Choose any point on the line and substitue in the above equation and we get the slope(m)
(-2 ,0)
0 = m*(-2) + 2
0 = -2m + 2
-2 = -2m
-2/-2 = m
m= 1

20 Points, Part A What percentage of the time margins are at least 0.6 second? Part B What is the most common margin of victory? (Screenshot)
Answer:
20%
0.5
Step-by-step explanation:
There are 20 margins, so you have to count how many are 6.0 or higher. There are 4 margins that fit this so you divide the 4 margins by 20, then multiply the quotient by 100. That's how you get 20%.
The most common time was 0.5.
8, 14.5, 21, 27.5, 34, 40.5 What’s the next number in the sequence
Answer:
47
Step-by-step explanation:
Determine if the sequence is arithmetic or geometric.
The difference between each term in the sequence is constant, so this is an arithmetic sequence.
To calculate the common difference, subtract one term from the next term:
14.5 - 8 = 6.5
21 - 14.5 = 6.5
27. 5 - 21 = 6.5
34 - 27.5 = 6.5
40.5 - 34 = 6.5
So the common difference is 6.5
To find the next term in the sequence, add 6.5 to the last term given:
40.5 + 6.5 = 47
