Question

if x &y are a pair of co interior angle formed when a pair of parallel lines are intersected by a transversal then the sum of x&y is 90 degre​

Answer 1

Step-by-step explanation:

if two lines are parallel ,

then the sum of two interior angles=180°

So,

90°. (Given)

let take x.

90°+x=180°

x=180-90

x=90°

THUS OTHER ANGLE IS=90°
