Sine rule! watch

1. Hello!

Sorry to be so noobish, but I've really got stuck on a sine rule question :L

How would I go about solving side x?

I can do all the other questions, this one just bugs me >.<

The angles in a triangle add up to 180, so you can easily find the third.

From there, it's just like any simple sine rule Q

What do angles in a triangle add up to?
EDIT: Too slow.

Yes, but I need side x

EDIT: OH DERP! SORRY!

Thanks! XD

The answers you have been given explain what to do. Is your problem that you don't know how to use the Sine Rule at all?

Yes, but I need side x
if a, b and c are the sides (with A, B and C being the opposite angles)

Sorry, I had an amazingly stupid moment there! I understand that I should have applied a little logic first :P

Thanks for everyone's help!

Thank you. Sometimes it's easy to miss the obvious point that I already have two angles!
