Problema Solution
A building is 3 foot from an 8 foot fence that surrounds the property. A worker wants to wash a window in the building 13 foot from the ground. He plans to place a ladder over the fence so it rests against the building. He decides he should place the ladder 7 foot from the fence for stability. To the nearest tenth of a foot, how long a ladder will he need?

drawn a right triangle, and you have a height of 13 and a base of 7 The formula for finding the hypotenuse (the ladder) is a^2+b^2=c^2, where a and b are the sides of the triangle. Plug in your values and do the math:
13^2+7^2=c^2 square the numbers
218=c^2 take the square root of each side
14.8= c answer
