4th angle = 360 - (120 + 60 + 50)
= 360 - 230 = 130

Answer:
120°+50°+60°=230°
360°minus 230°=130°
Step-by-step explanation:
hence, fourth angle is of 130° measure......
120°,50°,60° are three measures of the quadrilateral and the all four angles of quadrilateral is 360°. So, first sum all the three angles and then, subtract by 360°
