we know that sum of all interior angle of quadrilateral is 360degree
let the fourth side =x
so, 180 +80+60 +x = 360
320 +x =360
x = 360-320=40 degree
let the fourth side =x
so, 180 +80+60 +x = 360
320 +x =360
x = 360-320=40 degree

Angles of quadrilateral is 360gegree
Let, the fourth angle be x
Then, 180degree +80degree +60degree + x degree =360 degree
320degree+x= 360degree
X= (360-320)degree
X= 40 degree
Hence, the fourth angle be 40degree
