First you need to DRAW a triangle with angle A across from side A.
Now use the Law of sines to find the missing sides of the triagnle.
Law of sines - Wikipedia, the free encyclopedia
- Use the sine law to find angle B
- Find angle C (hint: all angles in a triangle add up to 180 degrees)
- Use the sine law again to find side c
Note the convention that sides a, b and c are opposite to angles A, B and C respectively
