Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
sum the 4 angles and equate to 360
x + 2x + 1 + 50 + 30 = 360 , that is
3x + 81 = 360 ( subtract 81 from both sides )
3x = 279 ( divide both sides by 3 )
x = 93
Then
∠ A = 2x + 1 = 2(93) + 1 = 186 + 1 = 187°
∠ B = x = 93°

Hence, the corrects answers are ∠ A = 2x + 1 = 2(93) + 1 = 186 + 1 = 187°
∠ B = x = 93°
