Question

please try to give me answer in step by step

Answer 1

Answer:

angle y = 108°----------(1)

angle x= 71° ---------(2)

Adding (1) and (2)

angle x + angle y = 71+ 108

angle x + angle y = 179°

angle x and angle y forms a pair of interior angles

Since, they are not supplementary line m is not parallel to line n.
