Answer 2

given:

<ADC = 120°

to find:

x = ?

solution :

<ADC + <ABC = 180° (sum of opposite angles of a cyclic quadrilateral is 180°)

120° + <ABC = 180°

<ABC = 180°-120°

<ABC = 60°

AND,

<ABC + x = 180° (linear pair of angles)

60° + x = 180°

x = 180° - 60°

x = 120°

so, the answer is 120°

hope it helps....
