And the posts just seem to multiply....

But the line between math people and non-math people is just an arbitrary
and unnecessary division.

Additionally(take that Ben) if you cant figure out the answer, sometimes,
you can prove that there is no answer!

I guess I can't forget what I never took. I only went to Algebra 2 and
then I was on to better things, like an extra PE period and
photojournalism.  Oh yeah, and I ended up being a sophomore in college
my senior year in high school because I took college courses at the
local magnet center.

Math frightens me, but I do like the fact that there is ALWAYS a right
answer.

I've got a tangent cheat table sewed into my climbing pack, a compass,
and a 100 ft string marked at 10 ft increments.

I use the table to figure out how tall things are.

height of object = tan(angle) * distance from object

I always amaze people who forgot all their high school trig.

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?
