Question

Line m || line l then find the value of y.

Answer 1

Answer:

$if \: m \: is \: prallel \: to \: l$

$so \: t \: is \: \: a \: transversal \: on \: it$

THEn,

$135 + y = 180$

$(alternate \: interior \: angles \: are180$

$y = 180 - 135$

$y = 45 \: degrees$

Answer 2

Answer:

Answer is 45°

Step-by-step explanation:

Both the angles are co-interior. So, their summation will be 180°.

Then, we can say that

135°+y= 180°

y = (180-135)°

y=45°
