Answer:
The sum of angles of quadrilateral is 360°
Step-by-step explanation:
let fourth angle be x
100+50+50+x=360°
200+x=360°
x=360-200
x=160°
Hence fourth angle obtained I.e.160°

Answer:
sum of angle of a quad. = 360
so..let the 4th angle by
100+50+50+x=360
200+x=360
x=360-200
x=160
4th angle of the quad is 160 degrees
