Answer 2

Answer:

Hey Seemir18, Here is Your Answer

yes, they are parallel

Step-by-step explanation:

The sum of angles in a quadrilateral is 360°,

So.. 2x + 90 + x + 3x = 360

6x = 270..... subtract 90

2x = 90...... divide by 3

Then angles A and B are both 90°, meaning sides AD and BC are parallel.

The same-side interior angles at transversal AB between lines AD and BC are supplementary, so the crossed lines (AD and BC) are parallel.

Answer:

The Value Of X Is 45°
