The complement of an angle is what, when added to it, equals 90°.
alpha%2Bbeta=90°
if alpha=%284x+-12%29°, then its complement is beta=90-%284x+-12%29°
=>beta=90-4x+%2B12°
=>beta=%28102-4x%29°

The supplement of an angle is what, when added to it, equals 180°.
alpha%2Bbeta=180°
if alpha=%284x+-12%29°, then its complement is beta=180-%284x+-12%29°
=>beta=180-4x+%2B12°
=>beta=%28192-4x%29°

so, if given angle %284x+-12%29°, its complement is %28102-4x%29° and its supplement is %28192-4x%29°
