Answer:
x = 90 degrees
Explanations:
The sum of interior angle of a heptagon is 900degrees. Taking the sum of all of the interior angles is:
[tex]93+166+127+112+x+76+113+123=900[/tex]
Simplify and solve for the value of "x"
[tex]\begin{gathered} 810+x=900 \\ x=900-810 \\ x=90^0 \end{gathered}[/tex]
