Two parallel lines are cut by a transversal. What is the measure of 26?

A. 180°
B. 90°
C. 123°
D. 57°

Answer 1

57

Explanation:

1+2=180

123+2=180

2=180-123

2=57

2=6=57 ( because 2 and 6 are 2 isotopic angles)

Answer 2

your answer will be option D.
Explanation:
123 + x = 180
x = 180 -123
x = 57
