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


ANSWER

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 $$=180-\left( 120+a-2b \right) =180-120-a+2b=\left( 60-a+2b \right) ^{ o }\\ 
$$.
