A boat heading out to sea starts out at
Point A, at a horizontal distance of 796 feet
from a lighthouse/the shore. From that
point, the boat's crew measures the angle
of elevation to the lighthouse's beacon-light
from that point to be 10°. At some later
time, the crew measures the angle of
elevation from point B to be 4º. Find the
distance from point A to point B. Round
your answer to the nearest foot if
necessary.

The distance from point A to point B is about 1211 feet.

What is trigonometric ratio?

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let h represent the height of the light house. At point A:

tan(10) = h / 796

h = 140.36 feet

At point B, let d represent the horizontal distance from B to light house:

tan(4) = 140.36/d

d = 2007 feet

The distance from A to B = 2007 - 796 = 1211 feet

The distance from point A to point B is about 1211 feet.
