A plane flies 830 miles from Franklin to Centerville with a bearing of 75°. Then it flies 684 miles from Centerville to Rosemount with a bearing of 32°. Draw a figure that visually represents the situation, and find the straight-line distance and bearing (from N) from Franklin to Rosemount. (Round your answers to one decimal place.)


I found the distance between Franklin and Rosemount which was 1409.7m

I can't find the bearing.

I got the same answer for distance.


Now use the law of cosines AGAIN to find the angle of the resultant (to which you will have to add 32)


830^2 = 684^2 + 1409.67^2 - 2(684*1409.67) cos c


solve for c   then add  32 degrees   to get 55.7 degrees
