If a 62 meterblighthouse spots a distress signal from a sailboat 135 meters from the base of the lighthouse. What is the angle of depression from the light?
Think back to right triangle geometry. For a right triangle, a^2 + b^2 = c^2 where c is the hypotenuse. If a lighthouse is 62m high (a) and a boat is 135m from the base (b), then find the depression of the light, or c. 62^2 + 135^2 = 22,069. Therefore, c = 148.55m. ChaCha!
