Answer:
x =12
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
30 + 4x+2 = 8+6x
Combine like terms
32 +4x = 8+6x
Subtract 4x from each side
32+4x-4x = 8+6x-4x
32 = 8+2x
subtract 8 from each side
32-8 = 8-8+2x
24 = 2x
Divide each side by 2
24/2 =2x/2
12 =x
