One of two adjacent angles has a measure of 45 degrees. If the whole angle is 75 degrees, how big is the other adjacent angle?

Adjacent angles are additive because they share a common edge and have the same vertex. Therefore,
75º = 45º + x
where x = the unknown angle.
Solving for x,
x = 75º − 45º = 30º
What adjacent angle and what whole angle?
