The bearing of a point P from another point Q is 310o. If |PQ| = 200m, how far west of Q is P?
-
A.
128.6m -
B.
153.2m -
C.
167.8m -
D.
187.9m
Correct Answer: Option B
Explanation
cos 40 = (frac{x}{200})
x – 200 x cosx
= 200 x 0.7660
x = 153.2m
cos 40 = (frac{x}{200})
x – 200 x cosx
= 200 x 0.7660
x = 153.2m
