Answer:

The sum of two angle is 180 (supplementary)

given angle = 3:1

first angle =3x

2 nd angle=1x

3x+1x =180

4x =180

x = 180/ 4

x = 45

so first angle =3x   x = 45

                   = 3×45

                    = 135 degree

2nd angle = 1x

               =45 degree

ans

Both angles are 135 and 45
