In a water park, people walk a distance of 20 meters up an inclined ramp before getting on a water slide. If the spot from where they start sliding down is located 7 meters above the water’s surface, calculate the angle of the ramp with the horizontal.

Answer 1

Y = 7 m.
r = 20 m.

sinA = Y/r = 7/20 = 0.35.
A = 20.49 Deg.

Answer 2

20.49
