Question

Find the supplementary angle of ${137}^o$.

• A. ${53}^o$.
• B. ${43}^o$.
• C. ${33}^o$.
• D. ${23}^o$.

Answer 1

The correct option is B ${43}^o$.

Two angles are said to be supplement of each other if they sum up to ${180}^o$.

Now supplement of the angle ${137}^o$ is ${43}^o$ as ${137}^o+{43}^o={180}^o$.
