I've been trying to figure out this for the past week.

It seems like the answer is painfully ovbious, but it confused me. ~.~;

Question:

Ed has a 5 m ladder in his garage. He wants to use the ladder to clean his eavestrough, which is 4 m above the ground. If he positions the ladder 1.5m from the base of his house, will the ladder touch the top of his eavestrough?

A diagram is given to assist you. Justify the Solution.
