Question

To get from the ship to the dock, Mae must walk up a ramp with an angle of elevation of 17°
and a height of 5.3 feet. To the nearest tenth, how long is the ramp?(1 point)
feet

Answer 1

Let the ramp length be h. Since sin(17°) = opposite/hypotenuse = 5.3/h,

h = 5.3 / sin(17°) ≈ 5.3 / 0.29237 ≈ 18.1 feet.
