Answer:

29

Step-by-step explanation:

We know that ABC and DEC are congruent this means that that the corresponding sides are equal and the corresponding angles are equal

BCA and ECD are vertical angles which means that if BCA = 48° then ECD=48°. We also know that CDE = 74° then DEC = 180 - (48 + 74) = 58 but ABC and DEC are congruent and the respective angle of ABC is DEC which means that 58 = 2x => x = 58 / 2 = 29°
