#### Answer

$23^{\circ}$

#### Work Step by Step

The trigonometric ratios are as follows:
$ \tan \theta =\dfrac{opposite}{adjacent}$
We need to use a scientific calculator and press the inverse tangent function $\tan^{-1}$
Suppose $\tan \theta =\dfrac{555}{1320}$
This gives: $ \theta \approx 23^{\circ}$
So, the angle of elevation is approximately $23^{\circ}$
