Question

The answer please of math

Answer 1

hey meet yes these lines are parallel because you see that angle hundred and which is in opposite means adjacent angle take it as angle one you will find the angle one value is equal to 80 means by the linear pair so when you will do by angle you will find the 80 and 80 and 80 are corresponding angles so there is forming a pair of corresponding angles and corresponding angles are only formed when the lines are parallel this proves that these two lines are parallel

Answer 2

yes the lines are parallel .

Explanation is below:

because supplementary angles form 180 degree.
According to question line l has the magnitude of 100 degree and line m has the magnitude of 80 degree.
Because alternate interior angles form 180 degree ; 100 degree + 80 degree = 180 degree

So, the lines l and m are parallel
