Question

Solve application problems using radical equations. How far from the base of the house do you need to place a 13-foot ladder so that it exactly reaches the top of a 10- foot tall wall?

Answer 1

c^2 = a^2 +b^2
a^2 = c^2 - b^2
a^2 = 13^2 - 10^2
a^2 = 69
a = root69

Therefore you need to put the ladder approximately 8.3 feet from the base of the house.
