A 10-foot tree casts a 17-foot shadow directly down a slope when the angle of elevation of the sun is 42o (see figure). Find \th

inna [77]

The angle of elevation of the ground is the angle between the ground and the line of sight

The angle of elevation of the ground is 30.46 degrees

<h3>How to calculate the angle of elevation</h3>

The angle of elevation is calculated using the following tangent ratio

$\tan(\theta) = \frac{10}{17}$

Evaluate the quotient

$\tan(\theta) = 0.5882$

Take the arc tan of both sides

$\theta = \tan^{-1}(0.5882)$

Using a calculator, we have:

$\theta$ = 30.46

Hence, the angle of elevation of the ground to the nearest tenth of a degree is 30.46 degrees
