Question

A 14 foot ladder is leaning against a building the base of the ladder is 5 feet away from the building how high up the building does the ladder reach

Answer 1

a^2+b^2=c^2

Explanation:

5^2+b^2=14^2

25+b^2=196

subtract 25 from both sides

b^2=171

take square root of 171

b=13.1

the ladder reaches 13.1 feet up the building
