Question

Lines l and m are parallel and intersected by transversals t and s as shown in the figure below.

What is m A) 180 degrees
B) 360 degrees
C) 540 degrees
D) 720 degrees

Answer 1

Angle W and Y are right angles and equal to 90 degrees each. Angle z and angle x are same side interior angles and they have a sum of 180 degrees because of the same side interior angles postulate.

so W= 90 Y=90 X+Z= 180 . so 90+180+90 =360 degrees. B.
