A24-foot ladder touches a building 20 feet up the wall. what is the measure of the angle the ladder makes with the ground? (acb)?

or 34 is the last option

I believe that the answer is 56. If you use trig, the equation becomes sin-1 (20/24). Punch that into a calculator and the answer is 56.4, so 56 is the closest answer.

45x is the correct answer
