Question

An 18-foot ladder is leaning against the side of a building forming a right triangle. The angle formed by the ladder and the ground is 60°. Which is closest to the distance, in feet, of the bottom of the ladder from the base of the wall?

Answer 1

The distance is 9 feet

Explanation:

18 is the length of the hypotenuse.

To find the length of the adjacent side, we take the hypotenuse multiplied by the cosine of the angle which is 60 degrees.

18*cos(60) = 9
