The supplement of the angle$(120 + a -2b)^o$ is $(60-a+2b)^o$State true or false:

True

SOLUTION
Two angles are supplementary, if their sum is ${ 180 }^{ o }$.
If one angle is $\left( 120+a-2b \right) ^{ o }$, then its supplement $=180-\left( 120+a-2b \right) =180-120-a+2b=\left( 60-a+2b \right) ^{ o }\\$.
