we have

<u>Find the greatest common factor GCF</u>
we know that

so
The GCF is equal to 
therefore

<u>the answer is</u>
The number is 
You have to use the fact that
for any value of
. So

where
is the positive acute angle you're looking for.
The
expression is: | x | = A + B + (A < C < B)
To simplify
the expression, write without the absolute value sign and we
would get this:
<span>x = A + B +
(A < C < B)</span>
