The interior of a triangle adds up to 180. All of these three angles therefore add up to 180.
x + 2x + 6x+18= 180
Add like terms
9x + 18 = 180
Subtract 18 on both sides
9x = 162
Divide 9 on both sides
x = 18

Find the value of x. Draw a triangle and label each interior angle before solving. Then find the angle measures of the polygon. Angle one: 2x°, angle two: xº, angle 3: (X + 8)°
