A helicopter is stationed at an airport H on a bearing 060 degrees and 800km from another airport P. A third airport is J is on bearing of 140 degrees and 1,200km from H.
Determine: i) the distance of P from J ii) The bearing of P from J
==========================
It's a triangle with 2 sides and the included angle given.
Angle H, or PHJ = 100 degs
Side h = PJ
=====================
Use the Cosine Law to find side PJ
h^2 = 800^2 + 1200^2 - 2*800*1200*cos(100)
------------------
ii) The bearing of P from J
Use the Law of Sines to find angle JPH
Add 60 degrees to angle JPH for the bearing.
