sam needs to clean the window on his house. he has a 25foot ladder and places the base of the ladder 10 feet from the wall of the house.
A) how high up the wall will the ladder reach?
B) if his windows are 20 feet above the ground, what is the farthest distance the baes of the ladder can be from the wall?

Use the Pythagorean Theorem.
a^2 + b^2 = c^2
10^2 + b^2 = 25^2
100 + b^2 = 625
b^2 = 525
b = 22.9 feet
Do the second problem using the Pythagorean Theorem.
