Question

 

Kelsy is visitng a museum and wants to know the height of one of the sculptures. She places a small mirror on the ground 19.2 feet away from the sculpture. She backs up 13.2 feet away from the mirror and knows her height is 5.5 feet. What is the height of the sculpture?

Answer 1

Draw and label a diagram!

The angle of incidence (light striking the mirror) is equal to the angles of reflection (the light leaving the mirror).

Two similar triangles are created.

s : 15.2 :: 5.5 : 13.2

Can you solve for s and answer?
