In this quadrilateral x=
A) 56. B) 67 C) 78 D) 89

Answer: B) 67.
Step-by-step explanation: You would add up all the angles you have which would be, 106 + 92 + 95 = 293. Then, you would take 293 and subtract it from 360, because that is the sum of all the interior angles in a quadrilateral. So the equation would be:
360 - (106 + 92 + 95) = x
360 - 293 = x
67 = x
