Annie walks 15 feet away from her house and places a mirror on the ground. She backs 4 feet away from the mirror so that she can see the tip of the roof. Annie's eyes are 5 feet above the ground. Annie and the house are both perpendicular to the ground. The angles between the top of the house, the mirror, and the ground and between Annie's eyes, the mirror, and the ground are congruent as shown in the image below:
Image depicts a mirror on the ground between a person and a house. The mirror is 4 feet away from the person and 15 feet away from the house.
What is the height of the house? S

Best ResponseYou've already chosen the best response.0let AC ( the height of man's eye)=5 ft, B be the position of mirror BE( the distance of mirror from house)=15ft Let height of house DE=x CB (the distance of man from mirror)+4 ft angle of incidence=angle of reflection.

Best ResponseYou've already chosen the best response.0AC is 5 ft B is the position of the mirror Be is 15 ft DE is x CB is 4 ft. So 5 over 4 equals x over 15. So 4x=75 and 75 divided by 4 equals x=18.75

Best ResponseYou've already chosen the best response.0In triangles ACB and DBE <ABC=<DBE (angle of incidence=angle of reflection) <ACB=<DEB (each right angle) so triangles are similar. Hence sides are proportional. \[\frac{ 5 }{ 4 }=\frac{ x }{ 15 },x=?\]
