The large angle = 120 degrees
Supplementary angles are two angles whose measures add up to 180°
Since we know from the ratio that one angle is twice the size of the other, the angles have to be 60 and 120.
2x=14
_ _
2 2
x=7
you are going to divide 2x by 2 to get the x alone. Then , you are going to do the same on the other side whcih is 14 by 2 = 7 . Last you will get you will answer x=7. Simple and Right !!!!
