I appears that you have a triangle PQR , with PQ = 15 km,
and angle P = 50°, angle Q = 80°
A quick mental calculation gives us angle R = 50° , making the triangle isosceles.
So without any work, QR = 15 km
by the sine law:
PR/sin80 = 15/sin50
PR = 15sin80/sin50
= ...
let me know if I misunderstood your description.
Villages p, q and r are situated as follows, p is 15km due north of q and the bearings of p and q are 50 degree and 80 degree respectively. Calculate the distance of r from p and q
