Question

An angle is 30° more than twice its supplement. Find the two angles​

Answer 1

Step-by-step explanation:

Let the angle be x.

Its supplement angle = 180-x

Therefore,

• x-2*(180-x)=30
• x-360+2x=30
• 3x=360+30
• 3x=390
• x=130

Answer : 130

Answer 2

Let the angle be X degree.

Then its supplement is (180-X) degree.

Given that, Angle - 2 x Supplement = 30.

X - 2(180 - X) = 30

X - 360 + 2X = 30

3X = 30 + 360 = 390

X = 390/3 = 130

Hence, the angles are 130 and 50 degrees.
