A 9.0m ladder rests against the side of a wall. The bottom of the ladder is 1.5m from the base of the wall. Determine the measure of the angle between the ladder and the ground, to the nearest degree
We know the hypotenuse [9] and the adjacent side [1.5]
So.....we can use the cosine inverse to solve this:
cos-1 [ 1.5 / 9 ] = about 80.4°
