Answer:

mark me as brainliest answer

Answer 2

Answer:

x=70°

Step-by-step explanation:

Drawing a line passing through T such that it is parallel to both AB and CD,

in this case x gets divided into 2 angles.

let the angles be a and b therefore a +b =x

a=180-140=40° (as it forms alternate interior angle)

b= 180 -150=30° (alternate interior angle)

therefore a+b=40+30=70° =x
