Brad is 1.7 m tall. He is looking at a building that he knows is 180 m tall. There is a 2 m tall wall between him and the building. When he is standing 12 m away from the wall, the top of the building is just hidden by the wall. a Show that the building is just over 7 km from the other side of the wall. b What assumptions have you made to calculate the distance?
