Question

A boat heading out to sea starts out at Point A A, at a horizontal distance of 862 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 15 ∘ ∘ . At some later time, the crew measures the angle of elevation from point B B to be 8 ∘ ∘ . Find the distance from point A A to point B B. Round your answer to the nearest tenth of a foot if necessary.

Answer 1

The boat traveled 781.5 feet from point AA to point BB

Explanation:

Find the height of the small triangle then find the base of the big triangle then subtract the two answers to find the distance between a and b
