In a parallogram the two angles on the same side ( Angle T and Angle C) equal 180 degrees

So we have 8x +29 + 2x +11 = 180

combine the like terms:
10x + 40 = 180

Subtract 40 from each side:
10x = 140

Divide each side by 10:
X = 140 /10
X = 14

Now we have X, replace X into the equation for angle C

2(14) +11 = 28 + 11 = 39 degrees

The 2 angles  add up to 180 degrees ( because the lines TK and CM are parall)

so we have

8x + 29 + 2x + 11 = 180
10x = 180 - 40
10x = 140

x = 14 (answer)
