Question

A bird catches a fish and flies 100 yards in a straight line at an angle of elevation x° from the ground. After flying for 100 yards, the bird drops the fish. The fish lands at a spot y yards horizontally from where the bird caught it. What is x?

A.cos-1 y/100
B.sin-1 y/100
C.tan-1 y/100
D.cos-1 100/y
E.sin-1 100/y

Answer 1

x = cos‾ ¹  (y ⁄ h)

                       x = cos‾ ¹  (y ⁄ 100)
That will be your answer
