3. A lighthouse is served by a ship's officer at a 42 degree angle to the path of the ship. And the next sighting the lighthouse is observed ata 90angle to the path of the ship. The distance traveled between sightings is 1800 m. To the nearest meter, what is the distance between the ship and the lighthouse at this second sighting?​

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

boxplot e is the answer

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
