8-66.

Sandip noticed that when he looked into a mirror that was lying on the ground 8 feet from him, he could see a clock on the wall. If Sandip’s eyes are 64 inches off the ground, and if the mirror is 10 feet from the wall, how high above the floor is the clock? Include a diagram in your solution.

Determine why the two triangles are similar. Remember triangles can be similar by AA, SAS, and SSS similarity theorems.

Set up a proportion. Are your units the same?
