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

Question

Options:

Answer: Option A
:

Given - the complementary angles are equal.

Let the angle be x. So its complement = x.
$\Rightarrow x + x = 90^{\circ}$
$\Rightarrow 2 x = 90^{\circ}$
$\Rightarrow x = 45^{\circ}$
The angle which is complementary to itself is $x = 45^{\circ}$ .
