Answer:
x = 15 degrees, one vertical angle is 165 degrees
Step-by-step explanation:
3x = x + 30
3x - x = 30
x(3-1) = 30
2x=30
x=15
All the angles need to add up to 360 degrees.
15 + 15 + 2y = 360
2y = 330
y=165

Step-by-step explanation:
What is the scale factor of the dilation?
Is the dilation an enlargement or a reduction?
Answers:
Scale Factor = 3/4
This is a reduction
======================================================
Explanation:
Let's focus on the point R(4,4). That's the preimage point for the image of R ' (3,3).
Let k be the scale factor. We multiply this value of k by the x,y coordinates of point R to jump to R '
we have x = 4 jump to 4k which is the x coordinate of point R'
So we set 4k equal to 3 and solve for k to get k = 3/4. The scale factor is 3/4 or 0.75
We have a reduction since the image triangle T'R'S' is smaller compared to the preimage triangle TRS. We can see that we have a reduction by looking at the scale factor. If 0 < k < 1, then we have a reduction. If k > 1, then we have an enlargement instead. So we go with the first option since 0 < 3/4 < 1 or you could say 0 < 0.75 < 1.
Answer:
A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement is a dilation that creates a larger image

Please if you do both I will give brainiest (to the first one to answer)
Answer:
Answer to first:
Yes, x is a rational number.Yes, y is a rational number.Y is largerAnswer to second:
I know that -3.4 is a rational number because it is an integer or decimal not equal to zero.
Step-by-step explanation:
Explanations to first:
0.147 is rational because you can write it out.0.147 bar is rational because it can be written as a fraction.Y is larger because the numbers keep repeating, so it has a larger value than 0.147.Jane is working on her tennis backhand in a gymnasium.

Ophelia keeps flour in a cylindrical canister. The capacity of the full canister is 75.36 in^3..When it is filled halfway the flour reaches a height of 3 in. What is the diameter of the canister?
Answer:
4 (rounded to the nearest whole number)
Step-by-step explanation:
total height = 3 x 2 = 6
Volume = radius^2 * pi * height
75.36= radius^2 * pi * 6
75.36/pi = radius^2 * 6
23,987833 = radius^2 * 6
23,987833/6 = radius^2
3,997972 = radius^2
radius = 1,999493
diameter = radius x 2 = 1,999493 x 2 = 3,998986

Can someone give me a small lesson on nets and surface areas??
Thank you if you can. I really don’t understand.
Hi!
Here is the definition of a net from www.icoachmath.com:
“Net is a two-dimensional pattern of a three-dimensional figure that can be folded to form the figure. In other words, net is a flattened three-dimensional figure which can be turned into the solid by folding it.”
In the photo is an example of a net of a rectangular prism.
Surface area is the measure of the total area of the surface of a 3D object. For example, if I have a cube, the surface area would be the area of the outside of the cube.
Hope this helped,

Solve the x
-9 (1/2x - 3) = 45
Answer:
=
−
3
6
7
Step-by-step explanation:
Answer:
x = -4
Step-by-step explanation:
-9 (1/2x - 3) = 45
Divide both sides by -9
1/2x - 3 = -5
Add 3 to both sides
1/2x = -2
multiply both sides by 2
x = -4
