5. Look at the circle on the coordinate plane below. Its equation is x2 + y2 = 625. The angle 0 is in standard position, passing through the point (15,20). a) What is the value of sin 0? b) What is the measure of angle 0? Round your answer to the nearest tenth of a degree. c) The sine of another angle in standard position has the same value as that in part a). Through what point on the circle does the terminal side of that angle pass (Circle the correct point)? (15,-20) (-15,20) (-15,-20) (-15,20)
