Question

A ramp 16 ft long rises to a platform that is 13 ft off the ground. Find x, the angle of elevation of the ramp. Round youranswer to the nearest tenth of a degree.

Answer 1

The figure can be drawn as,

The angle of elevation (C) can be determined as,

$\begin{gathered} \sin C=\frac{13ft}{16ft} \\ C=54.34^{\circ} \end{gathered}$

Thus, the required angle of elevation is 54.34 degrees.
