Question

The angles below are supplementary. What is the value of x? (5 points)

Answer 1

Answer:

Step-by-step explanation:

As the angles are supplementary, they sum up to 180

Hence, 3x+40+80=180

3x+120=180

3x=60

x=20

Answer 2

Like the person said above me the answer would be x=20 because 3x=60 just so you can have reassurance that they are right. :)
