Three towns P,Q and R are such that the distance between P and Q is 50 km and the distance between P and R is 90km. if the bearing of Q from P is 075° and the bearing of R from P is 345°, find the distance between Q and R, and bearing of R from Q

Answer 1

If you sketch it , you know two sides, and the included angle. Law of cosines to get the third side QR, and then the law of sines to get the interior angles, and for the final bearing, you should be able to add the angles to figure it.

Answer 2

The bearing of two points Q and R from a points P are 030 degree and 130 degree respectively. If PQ = 12cm and PR=5cm, find the QR

Answer 3

I don't understand
