Answer 2

Heya mate, Here is ur answer

Exterior angle = 120°

Interior opposite angles = 2: 3

Let the common ratio be x.

So, interior opposite angles are 2x and 3x .

We know that

By exterior angle property of a triangle

Exterior angle is equal to sum of interior opposite angles

120°=2x+3x

120°=5x

120°/5=x

24=x

So, angle 1 = 2×24

=48°

So, angle 2 =3×24

=72°
