A straight line is 180 degrees

- YoloShroom

alright so, we know that angle c is 56 degrees right?

- calculusxy

This a supplementary angle (meaning that the total degree of this angle is going to be 180). Remember that a straight is actually 180 degrees.
the angle of triangle DCB is 56 degrees and the other angle is unknown.
so what we need to do is
\[180 - 56 = x \]
x = measure of angle 1

Would I subtract 180 from 56?

- YoloShroom

Yes
