The bearing of two points Q and R from a point ... - WAEC Mathematics 1995 Question
The bearing of two points Q and R from a point P are 030° and 120° respectively, lf /PQ/ = 12 m and /PR/ = 5 m, find the distance QR.
A
13m
B
11m
C
9m
D
7m
correct option: a
x\(^2\) = 12\(^2\) + 5\(^2\)
x\(^2\) = 144 + 25
x\(^2\) = 169
x = \(\sqrt{169}\) = 13m.
