Question

A tree forms a right angle with the ground. If you place the base of a 12-foot ladder 3ft from the tree, how high up the tree will it reach?

Answer 1

Answer: 12.37ft

Explanation:

The formula to find the missing side of a triangle is a^2 + b^2 = c^2

so all you have to do is put 3 and 12

3^2 + 12^2 = c^2

9 + 144 = c^2

153 = c^2

√153 = 12.37
