Question

in figure 2.18,y=108°and x=71° are the lines m and n parallel? justify?

Answer 1

Hi ,

From the figure 2.18

Angle x and angle y are pair of

interior angles lie on same side of

the transversal.

Therefore,

If sum of x and y equals 180° then

m and n are parallel.

x + y = 71 + 108

= 180°

Therefore,

m , n are parallel.

I hope this helps you.

Answer 2

Answer:

in the given figure, given- angle y=71°, angle x=108°.

Step-by-step explanation:

To prove= line m and n r parallel.

proof= angle y and angle x are interior angles.

so, x+y=180°

But, 108°+71°=179°, which is not equal to 180°.

FA)hence, line m and n are not parallel to each other.

hope this helps. pls mark as brainliest. :)
