Question

Find the angle which is complementary to itself. [1 MARK]

Answer 1

Given - the complementary angles are equal.

Let the angle be x. So its complement = x.

$\Rightarrow x+x={90}^{\circ }$

$\Rightarrow 2x={90}^{\circ }$

$\Rightarrow x={45}^{\circ }$

The angle which is complementary to itself is $x={45}^{\circ }$.
