Answer:

C.
x=99^(\circ)

Explanation:

We have been given a image. We are asked to find the value of x.

We can see that our given figure is a quadrilateral. We know that all interior angles of a quadrilateral add up-to 360 degrees.


x^(\circ)+y^(\circ)+125^(\circ)+72^(\circ)=360^(\circ)

We can see that y and 116 degrees angles are linear angles, so we can set an equation as:


y^(\circ)+116^(\circ)=180^(\circ)


y^(\circ)+116^(\circ)-116^(\circ)=180^(\circ)-116^(\circ)


y=64^(\circ)

Substitute
y=64^(\circ) in the equation:


x^(\circ)+y^(\circ)+125^(\circ)+72^(\circ)=360^(\circ)


x^(\circ)+64^(\circ)+125^(\circ)+72^(\circ)=360^(\circ)


x^(\circ)+261^(\circ)=360^(\circ)


x^(\circ)+261^(\circ)-261^(\circ)=360^(\circ)-261^(\circ)


x^(\circ)=99^(\circ)


x=99

Therefore, the value of x is 99.
