Find angles in triangle if given one side and bearings

Postby Guest » Tue Apr 22, 2014 11:41 pm

My question is: Point B is South-East of point A at distance of 2km. From point A, a point P bears 57oT and from B, point P bears 348oT. Find the size of <PAB and <APB; I'm stuck and always missing an angle no matter how I project it. Appreciate any help.

I think the important thing is that South East means that B bears at an angle of 135 degrees from A. That means you now have all the angles and a side to do what uou need to do. :) :o
