In this parallelogram, by definition angles 2 and 3 are alternate interior and have the same measure, and angle 1 and 37degrees have the same measure. So angle 1 = 37. the other angle inside there that's not marked is supplementary with 63, so it measures 180 - 63 = 117. So angle 3, then, by the Triangle angle-sum theorem measures 180 - 37 - 117 = 26. As stated earlier, angles 2 and 3 are the same, so 2 is also 26. And I think we got them all! 1=37, 2 and 3 = 26.
Substitute it in with the pythagorean theorem. you’ll end up getting 6^2 + 12^2 + 13^2. this equation isn't true though, because 6^2 + 12^2 = 36 + 144 = 180 and 13^2 = 169.

Answer:
AC = 12x + 20
Step-by-step explanation:
Combine the terms:
AB + BC = AC
AB = 8x + 2
BC = 4x + 18
Plug in the corresponding terms to the corresponding variables:
(8x + 2) + (4x + 18) = AC
AC = 8x + 4x + 18 + 2
AC = 12x + 20
12x + 20 is your answer for AC.
