Question

find the complement of 2by3 of a right angle​

Answer 1

Given :- find the complement of 2by3 of a right angle ?

Solution :-

→ (2/3) of a right angle is = (2/3) of 90° = (2/3) * 90° = 2 * 30° = 60°

now, we know that,

• sum of two complement angles is 90° .

so,

→ complement of 60° = 90° - 60° = 30° (Ans.)

Extra knowledge :-

• sum of two supplement angles is equal to 180° .

Answer 2

Given:

Find the complement of 2/3 of a right angle.

Solution:

In geometry, The right-angle is an angle of exactly 90°

2/3 of a right angle mean:

$= > \dfrac{2}{3} \times 90^{\circ}$

$= > 60 ^{\circ}$

So, 2/3 of the right angle is 60°

Now, finding the complement of 60°:

• Two angles are said to be complementary angles when their sum equals 90°.

One angle is 60°

Let the other angle is x

=> 60° + x = 90°

=> x = 90° - 60°

=> x = 30°

Complement angles = 30° + 60° = 90°

Hence, the complement of 2/3 of a right angle is 30°
