If you have side a and angle A, and you want to work out the length of side b and you have angle b, the formula would be

b = sin B * (a/sinA)

In Javascript this can be done by

var B = 45; //size of angle B
var a = 5;  //length of side a
var A = 45; //size of angle A
var calculateLength = Math.sin(B/180*Math.PI) * (a/Math.sin(A/180*Math.PI));
