You are painting your house this summer. If the spot you are trying to reach is 15 feet up the side of the house and you can extend a ladder 6 feet from the base of the house, how long must the ladder be?

16.2 ft

Step-by-step explanation:

use pythagorean theorem

a² + b² = c²

6² + 15² = c²

36 + 225 = c²

261 = c²

Take ther square root of both sides

16.155494421403512 = c

Rounded

16.2 ft

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
