Answer 2

Answer :-

• The two supplementary angles are 99° and 81°.

Step-by-step explanation:

Assumption:

• Let us assume the two supplementary angles, which are in the ratio of 11:9 as 11x and 9x.

We know,

Supplementary angles measures 180°,

Therefore,

• 11x + 9x = 180°

⇒ 11x + 9x = 180

⇒ 20x = 180

⇒ x = 180/20

⇒ x = 18/2

⇒ x = 9

The value of x is 9.

∴ The angles are :-

• 11x = 11*9 = 99°
• 9x = 9*9 = 81°

Hence, The two supplementary angles are 99° and 81°.

Now, Verification

• 11x + 9x = 180

By putting the value of angles in L.H.S :-

⇒ 11x + 9x

⇒ 99 + 81

⇒ 180

Now, L.H.S = R.H.S = 180

Hence, Verified!
