Compass bearings of a carin are taken from two points A and B, 400 m apart, along a strsight north-south path, A being due north of B. the bearings of the carin from A and B are 110 degrees and 80 degrees, respectively. choose the two options which give the distances from A and B to the carin, correct to the nearest metre.

A. 402 m

B. 752 m

C. 757 m

D. 769 m

E. 787 m

F. 788 m

G. 877 m

H 878 m

is it F and G is this correct??

I marked C to be the cairn, and the angle C was 30ยบ

Using the sine law, I got AC = 788 and BC=752

which would be B and F
