Hello!
First, we represent the angle as x. That means the supplement is 2x.
Now, we will do the equation.
Equation:
2x+x=180 (because the sum of an angle and its supplement is 180)
Now, we will solve.
2x+x=180
3x=180
x=60
x=60
2x=120
Final Answer: the angle is 60 and its supplement is 120.
Is that clear?
Thank You!
