From the external angle property.
80 = sum of interior opposite angles
Therefore, 3:5 = 3x:5x
Now, 80 = 3x + 5x
80 = 8x
10 = x
3x = 30
5x = 50
By angle sum property the other angle is 100
So, the angles are 30, 50, & 100 degree
80 = sum of interior opposite angles
Therefore, 3:5 = 3x:5x
Now, 80 = 3x + 5x
80 = 8x
10 = x
3x = 30
5x = 50
By angle sum property the other angle is 100
So, the angles are 30, 50, & 100 degree
