Two angles are called complementaries if their sum is 90°.

So, the complement of an angle A is B, in which A + B = 90°.

Given A = 48°. Then:


48+B=90

To find B, subtract 48 from both sides:


\begin{gathered} 48+B-48=90-48 \\ 0+B=42\degree \\ B=42\degree \end{gathered}

Answer: The complement is 42°.
