Question

Ab parallel to cd find x

Answer 1

Step-by-step explanation:

AB & CD are parallel to each other. so that BD is perpendicular to both AB & CD.

=> B angle = 90-45 = 45 degree.

=> D angle = 90-30 = 60 degree.

so for finding x

=> x+45+60 = 180

=> x + 105 = 180

=> x = 75 degree

Answer 2

Answer:

first draw a line parallell to AB and CD. Then by alternate interior angles X = 75degree.
