Points X and Y are 20km North and 9km East of point O, respectively. What is the bearing of Y from X? Correct to the nearest degree.
-
A.
24° -
B.
56° -
C.
127° -
D.
156°
Correct Answer: Option D
Explanation
(tan theta = frac{9}{20} = 0.45)
(theta = tan^{-1} (0.45) )
= 24.23°
(therefore) The bearing of Y from X = 180° – 24.23°
= 155.77°
= 156° (to the nearest degree)
