Find the length of the hypotenuse. Use the Pythagorean Theorum. This is a right triangle and the two sides are √ 3 and 2√ 3.
So far I have this and I am pretty sure it is not right.
a^2 +b^2 =C^2
3^2+(2^2)(√ 3^2)=c^2
9+(2√ 3)(2√ 3)=c^2
9+(4)(3)=c^2
9+12)=c^2
c^2=21
c=√ 21

You are very close.  The only thing you did wrong was more like a typo, because you got the harder part right (b).  For (a) you did 3^2 when I know you wanted to do [sqrt(3)]^2.  If you make that correction, you will get the sqrt(15).  You obviously understand the concepts well.  Just be a little more careful on the steps.  Go a little slower and you'll be fine.

An easy way to see if I'm online is to do a "fan" of someone.  Then you are automatically notified.

He doesn't just give answers.  He takes time to explain, and that's the way Openstudy is supposed to be run.  I try to pick up tutoring tips from him.
