Answer:

58°

Step-by-step explanation:

angle ABC =180-120=60° ....LINEAR ANGLES

angle ACB= 62° ....... vertically opposite angles

angle x = 180-60-62=58° .....sum of all angles of triangle is 180°

Verified answer

Answer:

ACB = FCE = 62° ( Vertically Opposite Angles)

x + ACB = DBC ( Exterior Angles)

[tex]x + 62 = 120 \\ x = 120 - 62 \\ x = 58[/tex]
