As viewed from a cliff 340 ft above sea level a ship is 450 feet from the shore what is the angle of depression from the cliff to the ship on the water below

Angle depression = angle of elevation

To get the angle of depression we use the formula:

tan x=opposite/adjacent

where x is the angle of elavation

opposite is the height of the cliff

adjacent is the distance of the ship from the shore

thus

tan x=340/450

tan x=34/45

x=arctan 34/45

x=37.07

hence the angle of elevation = angle of depression=37.1°
