Question

The angles $x$ and $\left(90-x\right)$ are :-

• A. supplementary
• B. complementary
• C. vertically opposite
• D. making a linear pair

Answer 1

The correct option is B

complementary

Given angles are $x$ and $\left(90-x\right)$

Adding both the angles

$$\begin{gathered} =x+90-x \\ =90° \end{gathered}$$

When the sum of the measures of two angles is $90°$, then the angles are called complementary angles. In other words, if two angles add up to form a right angle, then these angles are referred to as complementary angles.

Hence, option B is correct
