1) Two planes fly from a point A. The angle between their two flight paths is 42 degrees. one plane has flown 35 miles from point A and the other has flown 20 miles from point A. How far apart are the two planes at this point?

2) A plane flies from A to B on a bearing of N75 degrees East for 810 miles. Then it flies from point B to point C on a bearing of N 32 degrees East for 648 miles. Find the distance from A to C.
