A ladder leans against a building. The angle of elevation of the ladder is 70. The top of the ladder is 25ft from the ground. To the nearest tenth of a foot, how long is the ladder?
Use the sin ratio to find the length of the ladder which is also our hypotenuse of the right triangle. sin70=25/x. Solving for x gives you x = 25/sin70. Do that on your calculator in degree mode to find that x = 26.6
