Your friend Tyler is preparing to climb a rock face and wants to figure out how far he will need to climb to reach one of three different peaks. You remember a trick you can use to help him out. You realize that if
you place a small mirror on the ground and move it to where Tyler can see the reflection of the peak in
the mirror, then the angles from the mirror to Tyler and from the mirror to the peak are congruent.
Use what you have learned about triangles, the mirror, Tyler, and the peak to find the height of the peak.
