So this is 15 feet. The distance between the base of the lamp and where the owl is going, where that mouse is right now, this is 10 feet. And if I were to think about where the shadow is, well, the light's emitting from right over here. The light's emitting right over here. And so the owl blocks the light right over there. So the shadow is going to be right over there. So if you just draw a straight line from the source of light through the owl, and you just keep going, and you hit the ground, you're going to figure out where the shadow is.
