7 - 4x + 4 = 20  ( not 7 - 4x + 1 = 20 ← - 1 is multiplied by - 4 )

Step 1 ← is incorrect → C

Answer:

C.

Step-by-step explanation:

interior angles for ABCD is 360° and for ABO(triangle above) is 180°

from triangle,

you will get angle for OBA which is 180° - 38° - 90° = 52°

from angle B, we know that, straight line is 180°.

so,

180° = 52° +y- 12°

y = 140°

so, we can calculate x.

360° = 90° + 90° + 128° + x

x = 52°
