An iced tea glass is 15 cm tall and has a diameter of 8.0 cm. The glass sits on a garden table on a sunny day and is completely filled to the brim with water. You are examining the glass and note that the sun is at an angle (theta) above the horizon to the left of the glass. The suns light reaches the top lip of the glass, and is refracted down into the water, and just barely makes it down to the water at the bottom right-hand side of that glass. What is the value of the angle (theta)?
