poor formula's
It is better to set them up like this...
Let's say we have a triangle and one angle a =63, angle b=90, and angle c=?? .
You'd set it up like this...
c = a + b - 180
assuming that all triangles have 180 degree we must deduct 180 from "a" and "b"
c = 63 + 90 - 180
c = 153 - 180
c = 27
.: When deducting 180 from 2 angles it will give you the last angle which in this case was 27.
