Hi1315idn

Answer:

[tex]x = 70 \degree[/tex]

Step-by-step explanation:

Sum of the interior angles in a quadrilateral is 360°

So,

[tex]x + 8 + 2x + 7 + x + x - 5 = 360\\ 5x + 15 - 5 = 360 \\ 5x + 10 = 360 \\ 5x = 360 - 10 \\ 5x = 350 \\ \frac{5x}{5} = \frac{350}{5} \\ x = 70 \degree[/tex]

Hope this helps you.
