1. We have no this reference triangle before our eyes because you missed to put the link for the picture . . .

2. Everybody knows and it is written everywhere that sin(60°) = sqrt%283%29%2F2.

Find sin 60 degrees without using a calculator by using ratios in a reference triangle.
If by "a reference triangle," you mean a special triangle, then use the 30-60-90 special right-triangle, and a hypotenuse of 1 to determine sin+60%5Eo
