# In Memoriam of Maryam Mirzakhani

Geometry Level 2

What is $x,$ in meters?

The cue ball starts 0.25 m below the top wall and 0.25 m right of the left wall. Assume that the ball and pocket are of point size and have no width, and that the angle of incidence equals the angle of reflection when the ball hits the wall.

Note: Iranian mathematician and Fields medalist Maryam Mirzakhani passed away on July 14, 2017 after a long battle with cancer. This is a tribute to her outstanding work in geometry and billiards dynamics.
