Let first and second angle be x
As we know the sum of all angles of a triangle is 180 by angle sun property
So 1x +2x +65=180
3x +65 =180
3x =180-65
3x=115
X=115/3
So angle 1=x =115/3
Angle 2=2x =230/3

Hope it will help you

Step-by-step explanation:

Angle sum property :

1x + 2x + 65 = 180

3x + 65 = 180

3x = 180 - 65

3x = 115

x = 115/3

x = 38.333

2x = 76.666
