A triangle has three sides a, b and c.
The angle opposite side a is A, opposite b is B and opposite c is angle C.
If:
a squared = b * ( b + c)
and
b squared = c * ( a + c )
and
The smallest side has a length of 1
Then the cache can be found at:
N B
E 000° (4 * a squared + 3 * b squared + 4 * c squared ) / 3
