Question

12) From the top of a lighthouse that is 150 feet above sea level, the angle of depression to a boat at sea is 30

degrees. To the nearest whole number, how far is the boat from the base of the lighthouse?

Answer 1

260 ft

Explanation:

Let the unknown length be x.

`\tan 30^(\circ)=(150)/(x) \\ \\ x=(150)/(\tan 30^(\circ)) \\ \\ x \approx 260</p><p>`
