Suppose m∠3 = 128 and m∠6 = (10x + 8). What value of x would result in a || b? A. 8.2
B. 4.4
C. 17.2
D. 12.0

x = 12

Step-by-step explanation:

The attached figure shows the measures of the angles. Here, line a is parallel to line b.

Given that,

m∠3 = 128 and m∠6 = (10x + 8)

We need to find the value of x.

Here,

(alternate interior angles)

So,

So, the value of x is 12. Hence, the correct option is (D).

Sry dont look at  this answer. I did it for points. :/
