Whether the calculation comes out in degrees or radians will depend on the
arcsine/arccosine/arctangent functions used. In CF, it's returned in
radians (as it should be!).
To convert radians to degrees, simply multiply by 180/pi.
So, in your example, the angle A in degrees would be
180/pi*arcsin(x/z)
or
180/pi*arccos(y/z)
or
180/pi*arctan(x/y)
which (should) all come out to be about
63.4 degrees.
did that help?

: Oh dear, I must be a little worse off than I thought.

: Taking a look at what you wrote has yielded little to me. 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?

: Sin(theta) = Opposite/Hypotenuse => Sin(A) = x/z
