1. The problem statement, all variables and given/known data
A light ray leaves point A in the figure, reflects from the mirror, and reaches point B. (Intro 1 figure) figure attached

How far below the top edge does the ray strike the mirror?

2. Relevant equations



3. The attempt at a solution

im not sure exactly where it says to mark?

Hi rayhan619!

You have to mark the point where the light hits the mirror

either use a theorem about reflection angles,

or draw the image of one and join it to the other.
