Answer:

110

Step-by-step explanation:

A quadrilateral's angles always add up to 360 degrees. This is because a triangle has 180 degrees, and a quadrilateral can always be split into two triangles.

This said, we can set up the following expression:

40+128+82+x=360

168+82+x=360

250+x=360

x=110
