Question

17. A person is looking at a boat on the water. The angle of depression from the person's eyes to the boat is 20 degrees. If the person's eyes are 1.5 meters above the water level, how far is the boat from the person?

A) 4.5 meters
C) 6 meters
B) 5 meters
D) 7.5 meters ​

Answer 1

Explanation:

I will assume you want the horizontal distance to the boat rather than the distance from the eyes to the boat

tan 20 = opposite leg / adjacent leg

tan 20 = 1.5 m / d

d = 4.12 m <====== I suppose answer 'A' is the closest answer
