Answer:

The elevation to the top of the building from the point on the ground where the shopper is standing is = 17.35°

Step-by-step explanation:

From the ΔABC

AB = height of the building = 250 feet

BC = 800 ft

Angle of elevation = $\theta$

$\tan \theta = \frac{AB}{BC}$

$\tan \theta = \frac{250}{800}$

$\tan \theta$ = 0.3125

$\theta = 17.35$ °

Therefore the elevation to the top of the building from the point on the ground where the shopper is standing is = 17.35°
