X is a point due east of point Y on a coast: Z is another point on the coast but 6√3km due south of y.
If the distance XZ is 12Km. Calculate the bearing of Z from X
A
240o
B
210o
C
150o
D
60o
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
Using sinØ = \(\frac{6\sqrt3}{12}\) → \(\frac{\sqrt3}{2}\)
sinØ = \(\frac{\sqrt3}{2}\) or 60^\circ
The bearing of Z from X = [270 - 60]^\circ → 210^\circ
