You start at 0 on the unit circle the cos of 0 =1, but at cos 0 there is no angle at all so there is no y value so at cos 0 y=0, 180 is the opposite direction of the starting point which is 0 so the x value of cos180= -1 but there is still no upward or downward angle ie.. y value. so the y value = 0 at 0 and 180. answer is 0
Answer:
B=58
Step-by-step explanation:
Complementary angles are angles where the sum equals 90°. So all you have to do is 90-32 and you get 58.
It has a rotational symmetry of 6
So minimum number of degrees = 360 / 6
= 60 degrees
