A 25-foot ladder is leaning against the side of a house. The top of the ladder is 20 feet above the ground. To the nearest degree, find the angle of elevation between the ground and the ladder.
Make sure your calculator is in DEGREE mode....
first divide opposite by the hypotenuse or 20 / 25
then multiply the answer by sine^-1
so your answer is D:
20/25 = 0.8
sine^-1 (0.8) = 53 and some change
