Answer 2

Answer:

The angles are 80° and 100°.

Step-by-step explanation:

Given : The difference between two supplementary angles is 20°.

To find : The angles ?

Solution :

Let the one angle be 'x'.

The difference between two supplementary angles is 20°.

i.e. the other angle be 'x-20'.

We know that,

The sum of supplementary angle is 180°.

So, $x+x-20=180$

$2x-20=180$

$2x=200$

$x=100$

The one angle is 100°.

The other angle is 100-20=80°
