angles are 4x 5x and 6x
4x+6x = 160
10x = 160
x = 160÷10
x= 16
4x = 64
5x = 80
6x = 96
4 angle will be 360- (64+80+96)
360-240 = 120
so fourth angle will be 120°
4x+6x = 160
10x = 160
x = 160÷10
x= 16
4x = 64
5x = 80
6x = 96
4 angle will be 360- (64+80+96)
360-240 = 120
so fourth angle will be 120°
