Question

A ladder is leaning against a building. Find the height at which the ladder is touching the building

13.9 ft

Explanation:

Since the triangle is a right triangle we can use pythagoreom theorm.

16^2=8^2+a^2 (a is the unknown side)

256= 64+a^2

192= a^2

Square root both sides and you get around 13.9 ft
