Question : 45

Total: 50

The bearing of two points Q and R from a point P are 030º and 120º, respectively. If | PQ | = 12 m and | PR | = 5 m, find the distance QR.

11 m
13 m
9 m
7 m

Solution:

△PQR is right-angled at P.

Using Pythagoras theorem:

QR

^2

= PQ

^2

+ PR

^2

= 144 + 25 = 169

QR =

\sqrt{169}

= 13 m
