A man standing at a top of a bridge looking down at boat that is out at sea.
The man is 2m tall, the bridge is 30m high, if the boat is 78m from the shore, find the angle of depression of the boat from the man.
:
A right triangle formed by the observer, the surface of the water below the bridge, and the boat
Find the interior angle (A) at the observer using the tangent
= 67.69 degree
find the angle of depression
90 - 67.69 = 22.31 degrees
