Answer:

  • 130°

Explanation:

First, I drew a line parallel to the two other lines.

  • Then, I knew that 50° was part of ∠1 and was a corresponding angle.
  • I also knew that the other angle was 80° because of the 180-angle property.

So then, I summed up both parts to get my answer. The measure of m∠1 is 130°. Please look at picture to learn more.
