C-06-Q182mediumsingle_mcq

If $\angle C$ and $\angle D$ are supplementary and $\angle C - \angle D = 60°$ , then $\angle C =$

a $100°$
b $110°$
c $120°$
d $150°$

ব্যাখ্যা

Supplementary angles satisfy $\angle C + \angle D = 180°$ . Adding this to $\angle C - \angle D = 60°$ gives $2\angle C = 240°$ , so $\angle C = 120°$ .
