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.
For a quadrilateral the sum of all the interior angle is equal to the 360 degrees.
The value of the [tex]x[/tex] is 14. Thus the option A is the correct option.
For a quadrilateral the sum of all the interior angle is equal to the 360 degrees.
Given information-
The given image shown in the problem is of a quadrilateral.
For a quadrilateral we know that the sum of all the interior angle is equal to the 360 degrees. Thus,
[tex]5x+110+70+110=360[/tex]
Simplify the above equation as,
[tex]5x+290=360[/tex]
Subtract by 290 from both the sides as,
[tex]5x=360-290\\5x=70[/tex]
Divide by 5 from both the sides,
[tex]x=\dfrac{70}{5}\\x=14[/tex]
Hence the value of the [tex]x[/tex] is 14. Thus the option A is the correct option.
