Question

Find the angle which is equal to its compleinent​

Answer 1

$\underline{\pink{ Complementary \:angles : }}$

Sum of any two angles are equal to 90° is called complementary angles .

$Let \: one \: angle = x\degree$

$Second \: angle = ( 90 - x ) \degree$

/* According to the problem given */

$x\degree = ( 90 - x ) \degree$

$\implies x\degree + x \degree = 90\degree$

$\implies 2x\degree = 90\degree$

$\implies x\degree = \frac{90\degree}{2}$

$\implies x\degree = 45\degree$

Therefore.,

$\red{ Required \: angle }\green { = 45\degree}$

Answer 2

Answer:

let the angle be x

complementary angle= (90-x)

so,

x=90-x

2x=90

x=45

45° is answer.

hope this helps you ☺️
