from the top of a 200 ft lighthouse, the angle of depression to a ship in the ocean is 23°. how far is the ship from the bas of the lighthouse?

Answer 1

The distance between base of lighthouse and ship is 84.89 feets.

What are trigonometric identities?

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

The distance between base of lighthouse and ship can be calculated using trigonometric functions:

Tan θ = opposite / Adjacent

Tan 23 = d / 200

d = 200 * tan23°

d = 84.89 feets
