A 16 foot ladder rests against the side of a house and the base of the ladder is 4 feet away. How high above the ground is the top of the ladder? Round to the nearestt tenth of a foot. A. 15.5 feet B. 16.5 feet C. 20 feet D. 240 feet

Respuesta :

First you use the Pythagorean theorem, you take 16squared minus 4squared equals b squared. 16 squared will  equal 256 and 4 squared will equal 16.
256 minus 16 is 240, take the square root of 240 and you get, (with rounding to the nearest tenth), 15.5 feet


Your answer is gonna be A. Or 15.5 feet!
