Name each pair of angles as corresponding, alternate interior, alternate exterior, or consecutive. Then solve for x.
Answer:
x = -2
Step-by-step explanation:
These 2 angles are alternate exterior so they're equal to each other.
x + 127 = 125
x = 125 - 127
x = -2

You can paint 8 square feet in 2 hours. How many square feet can you paint in 7 hours
8 square feet = 2 hours
°divide 2hrs to 8 square feet
1hr = ?
2÷8 =4
so,
1hr = 4 square feet
●In 1 hour 4 square feets will be covered•4 square feet can be painted in 1 hour.
*now to find how many square can be painted in 7 hrs.
°multiply no. of hours to hd no. of square feet per hour.
7hrs = ?
7×4 =28
So,
●28 square feet would be covered in 7 hours.may this helps you

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.
What is the value of x?
Answer:
x = 59
Step-by-step explanation:
combine all four angle measure expressions and set equal to 360°, then solve
x + x + 2x + 3 + 2x + 3 = 360
6x + 6 = 360
6x = 354
x = 59

What is the slope of (12,-18) and (11,12)? Please I’m very confused.
Answer:
-30
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.
Slope
[tex] = \frac{12 - ( - 18)}{11 - 12} [/tex]
[tex] = \frac{12 + 18}{ - 1} [/tex]
= -30

Find the length of each bolded ARC round to the nearest hundredth 5 mm and 232 Help ASAP
9514 1404 393
Answer:
20.25 mm
Step-by-step explanation:
Arc length is given by the relation ...
s = rθ
where r is the radius and θ is the central angle in radians.
There are π radians in 180°, so the arc length is ...
s = (5 mm)(232°×π/180°) = 20.25 mm
The arc length is about 20.25 mm.

Where exactly is <T?
Step-by-step explanation:
Either way I will say it's 66 degrees or cannot be determined. Either of those
Answer:
The answer to this question is 136
2. The dimensions of a rectangle can be given by x + 7 and x + 2. If the area of the rectangle is 66 square inches, what are the dimensions of the rectangle?
Answer:
(x+7)(x+2) = 66
x^2+9x+14=66
x^2 + 9x -52 = 0
(x+13)(x-4) = 0
x = 4 bc the other root, -13, can't be used (it would make the dimensions negative values)
A.45
B.30
C.90
D.180
E.40
F.55
G.130
H.50
Answer:
If you were to make a 360 degree circle and minus the 50 thats already there you get 310 the right angle on angle 5 is 90 degrees because its a right angle so then the 310-90=220 the obtuse angle on angle 2 is 180 so 220-180=40 lastly you share those forty between angles 3 and 4 and the solution is your answer.

Select the correct answer.
which equation matches the function shown in the graph?
A. Y = 1/2sin(x)
B. Y = sin(2x)
C. Y = sin(1/2x)
D. Y = sin(1/4x)
The equation for the graph is y = sin[(1/2)x] after applying the transformation x → (1/2)x option (C) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
A graph of a trigonometric function is shown in the graph:
From the graph of a function, we can see the sin function represented by the graph.
y = sin(x)
To find the equation for the graph we can apply the transformation to the above equation.
From the graph
x =2π
y = 0
x → (1/2)x
y = sin[(1/2)x]
Thus, the equation for the graph is y = sin[(1/2)x] after applying the transformation x → (1/2)x option (C) is correct.

2) Two angles in a triangle are 30 degrees and 40 degrees. Find the missing angle measure. Please show your math work step by step and don’t forget the unit.
there's a triangle with 40° on the top left corner with with a line on the edge and a 30° on the bottom right you need to find the missing angle for the bottom left
please help giving out 30 points please show ur work thank u <3
Answer:
Below
Step-by-step explanation:
The answer would be 90°
We know that every triangle should add up to 180°,
with that we can solve it!
30° + 40° = 70°!
180° - 70° = 90°!
30° + 40° + 90° = 180°
70° + 90° = 180°

A rock is dropped from a height of 100 feet. Calculate the time between when the rock was dropped and when it landed. If we choose "down" as positive and ignore air friction, the function is
Answer: 2.49 s
Step-by-step explanation:
Given
Rock is dropped from a height of [tex]h=100\ ft[/tex]
Using the equation of motion [tex]h=ut+\frac{1}{2}at^2[/tex]
here, [tex]u=0[/tex] (Rock is dropped)
[tex]a=g[/tex]
Putting values
[tex]\Rightarrow 100=0+\dfrac{1}{2}gt^2\\\\\Rightarrow t^2=\dfrac{2h}{g}=\dfrac{2\times 100}{32.2}\\\\\Rightarrow t=\sqrt{6.211}=2.49\ s[/tex]

How long is the wire that supports the tree?
5.6 ft
3.3 ft
Answer:
6.5 ft
Step-by-step explanation:
You must use Pythagoras theorem, which is a² + b² = c², then square root c to get answer
if 5.6 = a and 3.3 = b
5.6²+3.3²=42.25(=c²)
42.25 = c²
square root both sides
6.5 = c
Answer:
6.5 ft.
Step-by-step explanation:
To find this you can use the Pythagorean Theorem. [tex]a^2+b^2=c^2[/tex]
[tex]5.6^2 + 3.3^2=C^2[/tex]
31.36+10.89=[tex]C^2[/tex]
42.25=[tex]C^2[/tex]
NOW you have to square root both sides of the equation
[tex]\sqrt{42.25} = \sqrt{C^2}[/tex]
You square root both sides so you can get ride of the exponent on C
So, your answer is 6.5=C
hope this helps :)
p.s. for further questions, [tex]c^2[/tex], is always the opposite side of the right angle. :)
What is the answer X/7-3>8
Answer:
x > 77
Step-by-step explanation:
According to order of operations rules, we must carry out division before addition or subtraction. In this case we wish to isolate x and are permitted to simplify the inequality by combining the "like terms" 3 and 8, as follows:
X/7-3>8
+3 +3
--------------
x/7 > 11
The easiest way in which to solve for x is to multiply both sides of this inequality by 7:
7(x/7) > 7(11), or
x > 77
All numbers greater than 77 are part of the solution set.
