Question

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.
