Given that the two lines are parallel, we can assume that the two angles given are supplementary (due to them being same side interior angles)

Supplementary angles - when the sum of their degree measure is 180°

8x - 13 + 4x + 1 = 180

12x = 192

x = 16

Answer:

16

Step-by-step explanation:

angle 6 and angle 3 are supplementary angles

that means added together, they equal 180

so 8x-13 + 4x+1=180

12x-12=180   simplify by adding and subtracting

12x=192    simplify by adding 12

x=16 divide 192 by 12
