In a waterskiing competition, a jump ramp has a length of 25 ft. and the angle between the ramp and the water is 22° What is the height of the
ramp to the nearest tenth of a foot? Round your answer to the nearest tenths

Sagot :

Answer:  9.4 feet

Work Shown:

sin(angle) = opposite/hypotenuse

sin(22) = x/25

x = 25*sin(22)

x = 9.3651648353978

x = 9.4

Your calculator needs to be in degree mode. One way to check is to compute sin(30) and you should get 0.5 or 1/2.
