Answer 1

Answer: D.

Step-by-step explanation: Same side interior angles are supplementary, meaning they add up to 180. Thus, we can write an equation:

<1 + <2 = 180 --> (substituting expression values)

8x + 40 + 12x + 20 = 180 --> (simplifying)

20x = 120 --> (simplifying further)

x = 60

So, D.
