Question

Find the measure of an angle which is complement of itself.​

Answer 1

complementary angles are those whose sum is 90degree

so if we take an angle x

x+x=90

2x=90

x=45 degree

Answer 2

$\huge{\bigstar{\underline{\red{\large{\mathfrak{Answer:-}}}}}}$

$\sf{Let\: the\: measure\: of\: the\: angle\: be\: x°.}$

Since the sum of the measure of an angle and it's complement is 90°

$\sf{\blue{x° + x° = 90°}}$

$\sf{\blue{2x° = 90°}}$

$\sf{\blue{x = 45}}$
