Question

please answer quickly. It is very urgent please​

Answer 1

1.

the first one is parallel as the angles are equal..

2.101+81=182°

therefore the second one is not parallel.. as they should be a linear pair..

3.4x+6x+y=180

10x+y=180°......(1)

6x+y=x+5y

by transportation

5x=4y......(2)

therefore 10x=8y

by substituting value in equation (1)

8y+y=180

9y=180

y= 20°

bu putting values in equation (2)

5x=4*20

5x=80

x= 16°

please mark it as brainliest ❤️❤️ and follow me..
