30. Find the angle of depression from the top of a lighthouse 275 feet above water to a boat 1,324 feet

off shore.

Angle of depression is 78.27°

Step-by-step explanation:

The height of the light house = 275ft

Distance of the boat from the lighthouse = 1,324ft

The angle of depression = ?

To solve this question, we'll require a well detailed diagram to illustrate how the light house makes angle with the boat.

See attached document for better illustration

Using SOHCAHTOA,

tanΘ = opposite / adjacent

Opposite = 1,324

Adjacent = 275

tanΘ = 1324 / 275

tanΘ = 4.8145

Θ = tan⁻4.8145

Θ = 78.266°

The angle of depression is 78.27°

you probably already have the answer but anyways it's b. 15.0
