so he is currently 5 feet vertically form the wall
he is currently 3 feet horizonatlly from the wall
the ladder's base is 15 total feet from the wall
height:base=5:3
to find the total height
x:15
multiply 5:3 by 5
25:15
so the top of the ladders's vertical height is 25 feet
so the answer is the ladder is 25 feet from the ground
