Bearing problems
Hey guys! I really need your help to explain and show me how to do these problems. I was doing my hw and I have no idea how to solve these two. Thanks :)

1.Two ships leave port at 10:00 A.M. Ship #1 travels at a bearing of N 67° E (67° north of east) at 20 miles per hour and Ship #2 travels at a bearing of S 75° E at 25 miles per hour. How far apart are the ships at noon? (Round your answer to one decimal place.)

2.In tracking the relative location of two aircraft, a controller determines that the distance from the control tower to the first aircraft is 160 miles and the distance to the second is 110 miles. The angle between the two aircraft is 50°. How far apart are they? (Round your answer to one decimal place.)
