Lines r and s are parallel.
What is ? m<1?
A. 18º
B. 22º
C. 122º
D. 158º

Answer:
B
Step-by-step explanation:
Since r and s are parallel lines, then
The angle adjacent to 1 is corresponding to 158 and are congruent, thus
adjacent angle to 1 = 158°
1 and 158° are adjacent and supplementary, so
∠ 1 + 158° = 180° ( subtract 158° from both sides )
∠ 1 = 22° → B
