Answer:
140°
Step-by-step explanation:
The measure of angles of a quadrilateral is always 360°
Therefore,
120+50+50 + 4th angle=360
220 + 4th angle= 360
Fourth angle = 360-220
=140°

Step-by-step explanation:
sum of all angles of a quadrilateral is 360°
120° + 50°+ 50° + x = 360°
=> 220° + x = 360°
=> x = 360° - 220°
=> x = 140°
