A 15 foot ladder is leaning against a house such that the bottom of the ladder is 4 feet from the house. What is its angle of elevation

Respuesta :

Answer:

14 feet

Explanation:

15^2 = 4^2 + height^2

225 = 16 + height^2

height = sqrt(209) = 14.46 feet.

Rounding to the nearest foot, it is 14 feet.
