Question

In a quadrilateral three angles are 55°, 37º and 125° then what is the fourth angle?
​

Answer 1

quadrilateral of the fourth angle is 143°

Answer 2

Answer:

Let the fourth angle of the quadrilateral be x.

Now, 55+37+125+x=360.

So, 217+x=360.

So,x=360-217.

So,x=143.

So, fourth angle is=143°.
