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.

I don't know what you mean by "Solve the triangle" but I'm guessing you need to find the missing sides and angles?

- 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
