Question

an angle is 30 degree less than two times its supplement. find the angle

Answer 1

Let the supplement be x
So, the angle= 2x-30
According to the question,
X+2x-30=180
3x-30=180
3x=150
X=50
So the angle is 70

Answer 2

Answer:

110 degrees

Step-by-step explanation:

let the angle be x

so; x=2(180-x)-30

by solving ; equation

x=110
