We are given a quadrilateral inscribed in a circle, therefore, the sum of opposite angles is equal to 180 degrees, therefore:


\angle O+\angle M=180

Replacing the values we get:


100+x=180

Solving for "x":


\begin{gathered} x=180-100 \\ x=80 \end{gathered}

Therefore, the value of "x" is 80 degrees.
