Answer:

36.1 feet.

Step-by-step explanation:

From the diagram:

• The side length ,opposite ,angle 31° = x

,

• The side length ,adjacent to ,angle 31° = 60

Recall from trigonometry that:


\tan \theta=\frac{\text{Opposite}}{\text{Adjacent}}

This implies that:


\tan 31=\frac{\text{x}}{\text{6}0}

Cross multiply:


\begin{gathered} x=60*\tan 31\degree \\ x=36.1\text{ feet} \end{gathered}

The length of HI is 36.1 feet (to the nearest tenth of a foot).
