If a 30 foot ladder is positioned so that the bottom of the ladder is 1/4 of its length away from the wall, what angle does the ladder make with the ground

Step-by-step explanation:

Given that:

The length of the ladder = 30 ft

Distance between bottom of ladder and wall = of its length

To find:
