Answer:

56 feet

Explanation:

This is a trigonometry problem. It makes use of tangent. You can take the tangent of an angle and it will equal the side opposite divided by the side adjacent that isn't the hypotenuse.

In this case the angle is 35 degrees.

Tangent of the angle = opposite/ adjacent side

Tan(35) = (x)/(80)

Tan(35) = 0.7 so

(0.7)= (X)/(80)

Using algebra each side can be multiplied by 80.

(80)(.7)=X

56=x

X is in feet, so X is equal to 56 feet.

Hope this helps!
