Question

Choose the angles which are supplementary to each other.

• A.
• B.
• C.
• D.

Answer 1

Answer: (B), (C)

Measures of supplementary angles add upto ${180}^o.$
$\therefore$ Supplementary angle of ${130}^o={180}^o-{130}^o={50}^o$
Among the options, ${50}^o$ is not present.

Similarly, the supplementary angle of ${59}^o={180}^o-{59}^o={111}^o$
Among the options, ${111}^o$ is present.
Hence, ${59}^o$ and ${111}^o$ are the two supplementary angles.
