Point C has a bearing N 28 degrees E from point A and a bearing of N 12 degrees E from point B.What is the area of triangle ABC if B is due East of A and 25km from A?

You can use the law of sines to find the length AC, then law of sines again to find the distance from C to the east-west axis. From there just remember that the area of triangle ABC is one half the base (length AB) times the height (the distance from C to the east-west axis). Post back whet you get for an answer.
