A pilot leaves an airfield heading due east and flies 130 miles. she then turns to face a different direction, at bearing N A W (for some angle A between 0 and 90 degrees). in this new direction, she flies 100 miles, then turns to a bearing of S B W (for some angle B between 0 and 90 degrees.) after flying in this direction for 120 miles, she is back at the airfield where she started.

A) the overall flight formed a triangle. find the three angles in this triangle. (note: the angles in the triangle are not A or B.)

B) find the angels A and B
