Question

An angle is its own complement . The measure of the angle is.
(a) 30° (b) 45° (c)90° ​

Answer 1

Answer:

Correct option is

B

45

o

Let the measure of the required angle be x

o

.

Since, the angle is its own complement, both the angle and its complement will be equal.

Then,

⟹x

o

+x

o

=90

o

⟹2x=90

o

⟹x=

2

90

o

⟹x=45

o

.

Hence, the required angle measures 45

o

.

Therefore, option B is correct.

Answer 2

Answer:

$\huge\underline{\underline{\bold{\red{A}\green{N}\blue{S}\pink{W}\orange{E}\purple{R}}}}$

Step-by-step explanation:

45°

The measure of the angle that is equal to its complement is 45 degrees.

proving

x+x=90°

2x=90°

x=90/2

x=45°
