The answer is C
The reason being these two sets of angles are opposite angles (also known as vertical angles) and opposite angles are always congruent.
Pick a number. Any number. Call it 'x'.
Multiply 'x' by 4.
Add 10 to the product.
Call the current number 'y'.
The 'x' and 'y' that you have now are an 'answer' to that equation.
Do it as many times as you like. There are an infinite number of them.
The control group and the experimental groups are not comparable. They are selected from different districts.
Consider we need to find the dimensions and volume of the box.
Given:
The shape of the lamp is a rectangular prism.
It measures 14 high, 9 wide, and 3 long.
There is 1 all around the lamp for bubble wrap
To find:
The dimensions and volume of the box.
Solution:
Length of the box is:

Width of the box is:

Height of the box is:

Therefore, the dimensions of the box are 5 by 11 by 16 units.
The volume of the box is:

Where, l is length, w is width and h is height.
Putting
, we get


Therefore, the volume of the box is 880 cubic units.
Its the last choice
16x^2 - 8x + 1 = (4x - 1)^2
