solve both que step wise imp

Answer 1

$<b>HELLO !$

Hi here ur ANSWER

we know that
125+x=180(linear pair)

x=180-125

x=55

So l and m are parallel because alternate interior angles are equal.


2)

let in line m angle be y

then
y+125=180

y=180-125

y=55

NOW in line l let the adjacent angle form be "s"

so,
S+50=180(linear pair)

S=180-50

S=130

now
S+y=180(supplementary angle)

130+55=185

So, it is not supplementary angles because their sum is not 180

so l and m are not parallel.
