From a point P, the bearings of two points Q and R are N67ºW and N23ºE, respectively. If the bearing of R from Q is N68ºE and PQ = 150m, calculate PR
A
120m
B
140m
C
150m
D
160m
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
\(\frac{150}{PR}\) = tan45º
PR = \(\frac{150}{tan45º}\) = 150m
