Answer:
The value of x is 57
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In an inscribed quadrilateral, the opposite angles are supplementary
so
m∠B+m∠D=180°
substitute the given values and solve for x
[tex]93+(x+30)=180\\x+123=180\\x=180-123\\x=57[/tex]
therefore
The value of x is 57
