The student is not correct.
For angles to be coterminal, the difference between their measures must be a multiple of 360°.
The difference between 180° and –180° is 360°.
Angles with measures 180° and –180° are coterminal.
Answer:
Red Gold
Step-by-step explanation:
Assuming you mean 9/40
Red gold = 25%
Pink Gold = .2 which is 20%
Rose gold is

Answer:
294 cubic inches
Step-by-step explanation:
1) All interior angles of a square are right angles, so angle WER measures 90°
2) All squares are parallelograms, and diagonals of a parallelogram bisect each other, meaning PA=AE=8 cm. Thus, PE=16 cm
3) All squares are rectangles, and diagonals of a rectangle are congruent, meaning WR=16 cm. Then, using the fact that the diagonals bisect each other, we get that WA=8 cm
4) If we consider right triangle WPR, we know it is isoceles because all sides of a square are congruent. So, the length of WP is:
