To find the value of x, we can set up an equation using the fact that the two angles are complementary.
The sum of two complementary angles is 90 degrees.
So, we have:
40 + (8x+2) = 90
Now, let's solve for x:
40 + (8x+2) = 90
40 + 8x + 2 = 90
8x + 42 = 90
8x = 90 - 42
8x = 48
x = 48/8
x = 6
Therefore, the value of x is 6. So the correct answer is 6.
