A boat heading out to sea starts out at Point A, at a horizontal distance of 819 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 14∘ . At some later time, the crew measures the angle of elevation from point B to be 7∘ . Find the distance from point A to point B. Round your answer to the nearest foot if necessary.

Step-by-step explanation:

I've created a diagram and added steps on GeoGebra for reference. Please refer to the diagram below:

In any right triangle, the tangent of an angle is equal to its opposite side divided by its adjacent side (o/a).

Therefore, we have the two equations:

Because (reflexive property), we have:
