ANSWER
The sum of the interior angles is 540º
x = 64º
EXPLANATION
The sum the interior angles of any polygon follows the rule:
[tex](n-2)\cdot180º[/tex]
Where n is the number of sides of the polygon.
This polygon has 5 sides, so the sum of the interior angles is:
[tex](5-2)\cdot180º=3\cdot180º=540º[/tex]
Then, with this we can find x:
[tex]104º+120º+140º+112º+x=540º[/tex]
Solving for x:
[tex]\begin{gathered} 476º+x=540º \\ x=540º-476º \\ x=64º \end{gathered}[/tex]
