So the streetlight right over here is 20 feet high. So this is a 20 foot high street lamp. And right at this moment, and I haven't drawn it completely to scale, the owl is 15 feet above the mouse. So this distance right over here is 15 feet. And the mouse itself is 10 feet from the base of the lamp. Let me draw that. So the mouse is 10 feet from the base of the lamp.
