A jet leaves an airport on a bearing of N 77* W and travels for 243 mi. It then turns and continues on a bearing of S 13* W for 104 mi. Find how far the jet is from the airport to 3 decimal places.
If you make a sketch you will find that when the jet makes the turn, its new path is at 90° to its original path, so we have a right-angled triangle
d^2 = 243^ + 104^2
d = √..... =
