Question

I'd appreciate it if anyone could help out as soon as possible!

Which equation should be used to imply that l and p parallel?



Choices:


Question 5 options:

3x + 14 = 8x - 21


(8x - 21) - (3x + 14) = 90º


2 • (3x + 14) = 8x - 21


(3x + 14) + (8x - 21) = 180º

Answer 1

(3x + 14) + (8x - 21) = 180º

Explanation:

In order for the two lines to be parallel, the marked angles must be supplementary: their sum must be 180°.
