Let the 3rd interior angle be 180-80=100deg. so by angle sum property 5x +3x +100= 180 degree. therefore 8x=80 therefore x=10 and angle 5x=50 degree and angle 3x =30 degree

Let the required number be x
exterior angle=sum of interior opposite angles
80=5x+3x
80=8x
80/8=x
x=10
the anglesare 5x=50,3x=30
