Answer 2

Step-by-step explanation:

Sum of all the internal angles of a quadrilateral = 360°

Let's name all the angles as angle A ,B ,C ,D Given

that,

Angle A = 120°

Angle B = 70°

Angle C = x - 30°

Angle D = x + 20°

Now,

Angle A+B+C+D = 360°

120°+70°+x-30°+x+20 = 360

2x+180° = 360°

x = 360°-180° /2

x = 90°
