Two paths diverge at a 48 degree angle. Two mountain bike riders take seperate routes at 8 km an hour and 12 km an hour. How far apart are they after 2 hours?
---------------
That gives 2 sides and the included angle.
Sides are 16 km and 24 km.
The included angle is 48 degs
Use the Cosine Law to find the 3rd side.
