That website uses the formulas just as shown in the other question.  You don't have your calculator in radian mode or something, do you?

I plugged in a hypotenuse of 5 and input angle 30.  I got back side1 = 4.3301 and side2 = 2.5; side2/hypotenuse = 2.5/5 = 0.5 = sin(30).

Then type:
5 * 30 sin =
