Question

Tick ($\surd$)the correct answer in each of the following:

The pair of supplementary angles is:

• A. $52°,108°$
• B. $42°,138°$
• C. $146°,24°$
• D. $82°,10°$

Answer 1

The correct option is B

$42°,138°$

Two angles are said to be supplementary angles if sum of their measure is equal to $180°$.

Now, sum of:

$$\begin{gathered} 52°+108°=160°, \\ 42°+138°=180°, \\ 146°+24°=170°, \\ 82°+10°=92° \end{gathered}$$

Hence, the pair of supplementary angles is $42°,138°$.
