Hilary and Dale leave camp and go for a long hike. After going 7 km due east, they

the direction that Hilary and Dale should follow to reach their camp.
================
You have 2 sides and the included angle.
Use the Cosine Law to find the 3rd side - that's the distance from camp.

Then use the Law of Sines to find the other angles.
