Question

find x
plz tell with full formula​

Answer 1

Step-by-step explanation:

To find- x

To construct- draw a line parellel to AB and CD

angle 1=50°. (alternate interior angle)

angle 2+ 120°=180°( co-interior angle)

angle 2=60°

angle 1 + angle 2 + X - 20°= 360°

50 °+ 60° + x - 20° = 360°

110 - 20 + x =360 °

90° + X = 360°

X =360 °-90°

X =270°
