1. calculate the distance AC

2. Find the bearing of C from A

- trigonometry -
**Reiny**, Monday, April 23, 2012 at 11:50pmI made a sketch and got a triangle ABC where AB = 20

BC = 50 and angle B = 70°

by the cosine law:

AC^2 = 20^2+50^2-2(20)(50)cos70

= 2215.959...

AB =47.07 m

Using the sine law, find angle A
