Question 1200469
A car travels from town P for 50km due
North to town Q. It then travels 80km on
bearing of 270° to town R. Find: (a) The
shortest distance from town P to town R
(b) The bearing of town R from P (c) bearing
of P from R.
-----------------------
a)  It's a right triangle with sides of 50 and 80
d^2 - 50^2 + 80^2 = 8900
d = ~94.34 km
---
 b) & c)
tan(P) = 80/50
P = 58 degs
Bearing form P to R = 302 degs
Bearing from R to P = 360 - 302 = 058 degs
