A person is standing 50 ft from a statue. The person looks up at an angle of elevation of

Alekssandra [29.7K]

Answer:

The height of the statue is <u>21.4 feet.</u>

Step-by-step explanation:

Given:

Distance of the person from the statue = 50 ft

Angle of elevation of the top of statue = 16°

Angle of depression of the bottom of statue = 8°

The diagram is drawn below.

In triangle ABC:

BC = 50 ft, ∠ABC = 16°

Using trigonometric formula;

$\tan(16)=\frac{y}{50}$

$y=50\tan(16)$

$y=14.337\ ft$

Now, let us determine the height of man, 'x'.

Consider triangle BDE.

ED = 50 ft, ∠BDE = 8°

Using trigonometric formula;

$\tan(8)=\frac{x}{50}\\\\x=50\tan(8)\\\\x=7.027\ ft$

Now, from the diagram, it is clear that, height of statue is given as:

$H=x+y=14.337+7.027=21.36\ ft\approx=21.4\ ft(Nearest\ tenth)$
