A light beam shines through air and then strikes a mirror, making an angle theta = 62.0 degrees with respect to the vertical, as shown. The reflected beam then strikes a pane of glass of thickness h = 1.72 cm, located a distance y= 40.3 cm from the mirror, and then exits the glass pane at the bottom, a horizontal distance x cm away from where it struck the mirror. What is the value of x? 61.6 cm 77.0 cm 30.8 cm 107.8 cm
