#Answer is also solve in picture if u have any doubts in pic then see following down☆☆☆

Connecting AC, we get AB = BC And∠BAC= ∠ACB and ∠ACB = ∠BCE+∠ECA = 45° Let ∠a=∠ECA as the two ∆ADC and ∆DFG are congruent (the triangle that has sides 3, 1 and 10−−√) So, ∠ECA=∠FDG=∠a [∆ADC≈∆DFG By SSS]In ∆DOC, ∠DOC=∠x [Vertically opposite angles]∠DOC+∠OCD+∠CDO=180°Finally, ∠x = 180° −(∠a + ∠BCD ) (∠OCD=∠BCD , ∠CDO=∠a , ∠DOC=∠x) = 180° − (∠a + ∠ECB + ∠ECD) = 180° − 90° − 45° = 45° So, ∠x = 45°Hence Option (B) 45° is correct
