The front of an A-frame cottage has the shape of an isosceles triangle. It stands 19 feet high and is 20 feet wide at its base. What is the angle of elevation of its roof?

10/60

step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
