Question

A wheelchair access ramp has an angle of elevation of 24°. If the ramp reaches to the top of a 30 inch high porch, how long is the ramp?

Answers are either 12. 20 inches, 97. 38 inches, 73. 76 inches, or 32. 84 inches

Answer 1

Please sketch the figure to confirm my answer.

sin(24°) = 30/x

x sin(24°) = 30

x = 30/sin(24°) = 73.76 inches
