(not a right triangle)?

You know angle, or SAS.

you want the other distance (S)

I think I would start with the law of cosines:

c^2=a^2+b^2 -2ab CosC

**Bill**, Sunday, October 31, 2010 at 12:57pmOk. So c^2=100^2+b^2-2(100)b Cos100 ?

**Bill**, Sunday, October 31, 2010 at 1:05pmc^2=100^2-x+(-12t)^2-2(100-x)(-12t) Cos100 or maybe this?

**Bill**, Sunday, October 31, 2010 at 2:36pmStill trying to figure this out.

Am i going in the right direction?

c2=(12t)^2+(10t)^2-2(12t)(10t)Cos100
