Captain Black is on a fishing boat that leaves its pier and heads east. After traveling for 30 miles, there is a report warning of rough seas directly south. Captain Black turns the boat and follows a bearing of S45D.W [South 45 Degrees West] for 12 miles.
1.At this time, how far is Captain Black from the boat's pier?
2.What bearing could the boat have orginally taken to arrive at this spot?
Could someone tell me how to do these two problems? it gets me soooo...... !
