if the angle of elevation at B is 22.3° then angle B in your triangle ABC is its supplement: 157.7°. b = 1503 sin157.7° / sin5.4° = 6060

My diagram has triangle ABC with the interior angle at B equal to 54.3 and the interior angle at A equal to 35.7 (the bearings as given would not be inside the triangle as given) BTW, angle C = 90 Your answer is what I got for the distance to A, the distance to B would be 5.064

They tell you that the legs of the right triangle are 6 and 8. It is obvious that the height of the triangle would be the 6, and the length would be the 8. With the given numbers 6 and 8, you can tell that we are going to be increasing by 2, which is where we get the 10 from ...
