Answer 1

Answer:

mark me as brainliest

Step-by-step explanation:

first of all this is parallelogram not a trapezium.

x-22+x+42=180(the sum of adjacent angles of parallelogram is 180)

2x+20=180

2x=160

x=80

Answer 2

Answer:

The answer to your question is 80

Step-by-step explanation:

Since ABCD is trapezium

AB||CD

So, Angle A + Angle D = 180° [alternate interior angles]

x-22+x+42 = 180

2x + 20 = 180

2x = 180 - 20

2x = 160

x=80
