Find θ if d is 2.6 miles.

Question

The radar on a ship picks up two shipwrecks, A and B, 5.12 miles beneath the surface. The distance between the shipwrecks is 1.25 miles. The angle of depression to Shipwreck B depends on the horizontal distance, d, from the ship to Shipwreck A. Find \thetaθ if d is 2.6 miles. Round to the nearest tenth.

Write ONLY your numeric answer. You do not need the degree symbol.

Answer 1

I can't copy a drawing here but phi is the angle of depression and theta is the angle upwards from B
