Question

in figure 10.11 l|| M||n . find angle X and Y​
show proof

Answer 1

Answer:

y = 30 as alternate interior angle

x = 130 as transversal intersect parallel lines so the interior angle of the same side is supplementry

Answer 2

Answer:

x = 130 degree and y = 30 degree.

Step-by-step explanation:

angle x and angle lAB are interior angles and their sum is 180 degree.

so x + 50 = 180

Hence x = 180 - 50

           x = 30 degree.

Angle nCB and angle y are alternate interior angles and they have equal values.

Hence angle nCB = angle y = 30 degree.
