The angles below are supplementary. What is the value of x?<br><br><br> 5<br> 7.5<br> 15<br> 30
OLEGan [10]

Answer:

x=30

Step-by-step explanation:

The two angles are supplementary.  They add to 180

4x+20 + 40 =180

Combine like terms

4x+60 =180

Subtract 60 from each side

4x+60-60 = 180-60

4x = 120

Divide each side by 4

4x/4 = 120/4

x = 30
