Word problem issues. Problem: There is some sunken treasure and Blackbeard wants it, yet Jack Coostoe has sent out two ships (one is a decoy) to get the treasure first. The only information provided as to the location of the treasure is that it's 2.18 degrees (angle of descent) from the port to the treasure. The point of the problem, with information about the path each of the two ships takes, is to find which problem has an angle of 2.18 degrees descent yet has a depth of 1 km or less (diving). **I realize which is the actual ship since I solved the problem, but I have to do a write-up and I'm not sure whether to include part B.** Goldrush: left port on a due east heading for 15 km then turned toward a bearing of N 35 degrees E for 27 km. The Goldrush dropped anchor there, but sent a mini submarine in the same direction as a line going from port through the Goldrush. The sub descended at a 48 degree angle for 2 km. A) How far from port was the Goldrush when they dropped anchor? B) How far was it from the shore to the final location of the sub? (IS THIS NECESSARY IN THE WRITE-UP?) C) What was the angle of descent from the shore to the final location of the sub? (It was 2.18 degrees, making it the real ship after the treasure) If the point of a story math problem is to find an angle of descent regarding a non-right triangle, then is it necessary to find the length of x if the triangle had been a right triangle?
