The given figure is a quadrilateral  .In a Quadrilateral sum of angles is 360 degrees.

The given four angles in the quadrilateral are 70°,110°,110° and 5x °.

Applying angle sum property of quadrilateral:

70+110+110+5x=360°

Adding ,

290+5x=360

Subtracting both sides by 290 so that  x term can be isolated,

290-290+5x=360-290.

5x=70

Dividing both sides by 5

x=14.

Value of x is 14.
