Label each diagram as angle of depression or angle of elevation. horizontal line line of sight line of sight HO horizontal line 2. Dyani attempts to find the area of AABC. What is her error? Find the correct area. Round to the nearest square centimeter. 12 cm b area = }(AB)(BC) tan C area = (14)(12) tan 65 65 ~ 180 cm2 a 14 cm x ft 3. A lifeguard, seated 10 ft up, is looking 550 down at a swimmer. Her line of sight forms 10 ft a 55 angle with the horizontal line. How far is the swimmer from the base of the lifeguard stand? Given information: Angle of depression is Use the ratio. The length of the side opposite the tan - X angle of depression is ft . X = N The length of the side adjacent to the tan angle of depression is ft. enVisionTM Geometry . Teaching Resources
