You want the ArcSine of the Opposite side divided by the Hypotenuse side. And what are these radian things you talkin' 'bout? Ignore them. They were just a rumor. Like the metric system.
So, Angle=Arcsine(oppositeSide/Hypotenuse) Now back to those pesky radians. Cold fusion ASin function returns radians In your example below... <cfset AngleInDegrees=aSin(x/z)*(180/pi())> Does this make any more sense?

I think I may be confused over units, and perhaps converting radians to degrees improperly. Would you mind stepping me through your formulas? Say if, in triangle ABC, where B is a right angle and z is the hypotenuse, when BC is x and AB is y, we have a value of 5 for y and 10 for x. How do I apply these calculations to determine the angle of A in degrees?
