Iteru [2.4K]

Answer:

x = 50°

Step-by-step explanation:

sum of all angles of a quadrilateral is 360°

so, the other unknown angle be y

=》y + 40° + 110° + 80° = 360°

=》y + 230° = 360°

=》y = 360° - 230° = 130°

and the unknown angle + x = 180°

( because they for linear pair )

so, x + y = 180°

x + 130° = 180°

x = 180° - 130° = 50°

hence, x = 50°
