Question

Write the complement angle of:​ (i) ${45}^{\circ }$.

Answer 1

We know that , two angles are said to be complementary if their sum is ${90}^{\circ }$.

Let , the complement angle be $x$.

$\therefore$ $x+{45}^{\circ }={90}^{\circ }$

$x={90}^{\circ }-{45}^{\circ }={45}^{\circ }$

Hence, complement angle of ${45}^{\circ }$ is ${45}^{\circ }$
