Question

Plzz explain and answer.

Answer 1

Let angle p be x

Now as

It us given that supplement differ by 20°

So,

180-20

=160

Now as they are supplementary to each other

Therefore

X+160=180

X=20

Hence angle p =20°

Answer 2

Here supplement angle of p is 180-p
As per question, p-3(180-p)=20
or, p- 540+3p=20
or, 4p=560
or,p=560/4=140
so angles are 140 and 40
