Question

one third of an angle is 20 degree more than its supplement.. find the angles​

Answer 1

Answer:

So we can say that x - 20 = 180 - x because we would have to subtract 20 from x to equal its supplement. So let's add x, and also add 20 to both sides, so we now get: 2x = 200, so x = 100 deg ANSWER Easy to check: x= 100, so its supplement = 180 - 100 = 80.

Answer 2

Answer:

1st no.= 150

2nd no.= 30

Step-by-step explanation:

x/3=180°-x+20°

x/3=200°-x

x=(200°-x)3

x=600°-3x

3x+x=600°

4x=600°

x=600°/4

x=150°

Other number= 180°-150°

= 30°
