The distance of a boat from a bridge 120 m high above sea level is 200m. Calculate the angle of elevation of the bridge from the boat. SO HARD GUYS. PLEASE HELP.

Answer 1

not so hard if you
(a) draw the diagram
(b) review your basic trig functions. The angle θ has
tanθ = 120/200 (if the distance on the water is 200m)
sinθ = 120/200 (if the line-of-sight distance is 200m)
