Question

Nevaeh leans a 22-foot ladder against a wall so that it forms an angle of 64 degrees with the ground. How high up the wall does the ladder reach? Round your answer to the nearest hundreth of a foot if necessary

Answer 1

19.77 ft

Explanation:

The ladder is the hypotenuse of a right triangle ....one leg is the house , the other leg is the ground.

sin 64 = opposite/hypotenuse = height /22

sin 64 = height / 22

22 * sin 64 = height = 19.77 ft
