I can help you with that!

So she walked away 15 feet from the house and put a mirror on the ground and she backed away 4 feet. We can get a ratio of 4/15 and if we divide 4 by 15 we get 3.75. That means the smaller triangle in the picture is 3.75 times smaller than the big triangle. So to get the height of the house we can simply multiply 5 which is Annie's height by 3.75(Because Annie is the height of the small triangle and the height of the bigger triangle is the height of the house)! You can do that yourself :)
