This is a practice assessment! Therefore it isn’t for a grade . I just need help solving this

Answer 1

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.
