Pete is standing on the roof of a building and sees Laura below at an angle of depression . If the roof of building is 12ft high, how far is Laura from the school? Include a diagram as part of your solution.
+36916 You need to post the angle of depression....it is missing in your post 
+36916 tan 80o = opposite / adjacent
= 12 / distance
12 ft / tan 80o = distance in feet =2.12 ft
