Eric is locked out of the house. The only open window is on the second floor, which is 12 feet above the ground. He needs to borrow a ladder from a neighbor.
a. If he must place the ladder 5 feet from the house to avoid some bushes, what
length of ladder does Eric need?
b. How do we know the ladder, house and ground form a right triangle?
c. If the neighbor only has a 15-foot ladder, how far from the house will Eric need
to place the base in order for the top of the ladder to be at the window?
