Question

Guys pls give me the correct answer with steps plssss pls help.​

Answer 1

Answer:

y + 135° = 180° ( Co - interior angles )

=> y = 180°-135°

=> y = 45°. ans......

Answer 2

$\huge\sf\red { Given }$

• ' m || l ' and 't' is transversal

• One angle is given 135° ( suppose it as ∠1)

$\huge\sf\blue { To\: find- }$

• Value of angle y. ( suppose it as ∠2)

$\huge\sf\pink { Concept \: used-}$

Both ∠1 ( 135° ) and ∠2 is making Co interior angles.

[ Co-interior angles lie between two lines and on the same side of a transversal. ]

✴ If the two lines are parallel, then co-interior angles add to give 180° ✴

It means that ∠1 + ∠2 = 180°

$\huge\sf\orange {Solution-}$

Since ∠1 and ∠2 is forming co interior angles , so

$\rm\purple {\implies 135° + y = 180° }$

$\rm\purple {\implies y = 180° - 135° }$

$\rm\red {\implies y = 45° }$

$\huge {\boxed {\rm {\orange { y = 45° }}}}$
