Answer 1

You need the Law of Cosines here, since you only have 1 angle measure.  If you had 2 you could use the Law of Sines, but nevertheless, we'll get there.  The Law of Cosines for our particular set of info looks like this: $x^2=65^2+41^2-2(65)(41)cos(35)$.  Simplifying a bit we get $x^2=4225+1681-4366.080396$ and $x^2=1539.9196$.  Taking the square root of that and considering the principle root only, x = 39.2, second choice down.
