Well you have to add
+8 which makes 12 so add 12 and you get 24

The answer would be 16 sq yds!

The formula for finding the area of a triangle is:

a = $\frac{1}{2}$ lh
Where l is the length of the triangle and h is the height.

So the formula would be a = $\frac{1}{2}$ 4*8 which equals 16!

A person is standing 50 ft from a statue. The person looks up at an angle of elevation of 8 degrees when staring at the top of t

The height of the statue is 19.5 feet.

Why?

We can solve the problem using trigonometric formulas. In this case, we are going to use the trigonometric formula of the tangent.

We know that the person is standing 50ft from the statue, so, it will be the base of the two triangles formed by both angles (elevation and depression)

Using the trignometric formula, we have:

First triangle:

$tg(\alpha )=\frac{h_{1}}{base} \\\\tg(8\°)=\frac{h_{1}}{50ft}\\\\0.14*50ft=h_1\\\\h_1=7ft$
