dont give me wrong answer .

Step-by-step explanation:

I don't know answer but this is not wrong answer

now I'm asking yourself

Answer 2

Let x be the measure of the fourth angle.

We know that the sum of the interior angles of a is 360 degrees.

We'll use this fact to find the measurement of the fourth angle of the quadrilateral .

We have been given that two angles are 55 degrees each and the third angle is 140 degrees. Hence, we have

70+70+200+x=360

x+340=360

x=360−340

$\red{x = 20}$

Therefore, the measurement of the fourth angle is 20°.
