Question

find complement of 1/3 right angle write correct answer
$1 \3$
​

Answer 1

Answer:

We know that, if two angles are complementary, then their sum is 90

o

.

Then, the complement angle of

2

1

of right angle =

2

1

of 90

o

is,

=90

o

−(

2

1

×90

o

)

=90

o

−45

o

=45

o

.

Therefore, the complement angle of

2

1

of 90

o

is 45

o

.

please make as brilliant and thanks

Answer 2

Explanation:

Let the required angle be x.

According to the question,

⇒ (180

o

−x)=(90

o

−

×90

o

)

⇒ 180

o

−x=90

o

−30

o

⇒ 180

o

−x=60

o

⇒ x=180

o

−60

o

⇒ x=120
