BEARINGS, CAN SOMEBODY PLEASEE HELP ME.. I HAVE A TEST AND IT DUE IN 3 HOURS

Question

From airport p, a plane flies 200km on a bearing of 142•(degrees) to airport R, it then flies 140km from Airport R to airport S on a bearing of 52• (degrees)

1) Draw a diagram to represent the journey of the plane

2) Determine the size of angle PRS

3) Calculate the size of angle SPR to the nearest degree

4) determine the bearing of s from p

if it’s possible, can you please show the working? Thanks in advance🙏🏽

Answer 1

On the x-y plane, positive y is North, positive x is East, negative y is South, and negative x is West. A bearing of 0 degrees is pointing "up." As you increase the bearing angle, you move clockwise in circle fashion. A bearing of 142 degrees will put you in the 4th quadrant at R, respective of p. At R "up" is again 0 degrees, so a bearing of 52 degrees will put you in the 1st quadrant at S, respective to R. So think of carrying a compass with you - wherever you are, North is always North when thinking about bearings.
