Answer:

65°

Explanation:

Angles in any quadrilateral add up to 360

So we can make a equation:

[tex]360 = 2(18b-11)+2(9b+2)[/tex]

[tex]360=36b-22+18b+4[/tex]

[tex]360=54b-18[/tex]

[tex]378 = 54b[/tex]

[tex]b = \frac{378}{54}[/tex]

b= 7

So now you substitute b with 7 to give you:

[tex]9(7)+2[/tex]

[tex]63+2[/tex]

65°
