Answer 1

<1=97°

steps:

<1+83=180 co interior angle

<1=180-83=97°

Answer 2

m<1 = 97°

Explanation:

<1 and 83° are same-side interior angles. Same-side interior angles are supplementary. This implies that:

m<1 + 83° = 180°

Therefore:

m<1 + 83° - 83° = 180° - 83° (subtraction property of equality)

m<1 = 97°
