A billboard is rectangular in shape. The banner design has a line along its diagonal of length 35 feet. The length of the banner is 25 feet. Which expression can be used to find the width of the banner?
Technically the answer would be the square root of your expression. I assumed you used the Pythagorean theorem to derive the expression.\[w=\sqrt{35^2-25^2}\]
