C can be found using pythagoras theorem. c2=a2+b2. Now, b is not given, but we know that cos(theta)=b/c=>b=c*cos(theta). Substituting b in the above relation, c2=a2+c2(cos(theta))^2=>c2=a2/(1-cos((theta))^2). c is the squareroot of c2. Hence c=sqrt(2/(1-cos((theta))^2))

Rule for dividing fractions...
(a/b) / (c/d) = (a/b)*(d/c) = (ad)/(bc)
in this case:
(3/5)/(1/2)=(3/5)(2/1)=6/5=1 1/5=1.2
