Answer:
X = 14
Step-by-step explanation:
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 1
