Question

A ladder, 14 feet long, is leaning against

a building. If the base of the ladder is 7
feet from the building, how high up the
building will the ladder reach?

Answer 1

12.6

Explanation:

I rounded to the nearest tenth of a foot like it said to :)

Answer 2

12.12ft

Explanation:

14² = 7² + x²

x² = 14² - 7²

x² = 196 - 49

x² = 147

x = √147

x = 12.12ft
