Let the interior angle be x
Then the exterior angle would be 3x.
these two angles would form a straight line and we know that the straight angle is equal to 180 degrees. This can also be called a linear pair.
x+3x=180 degrees
4x=180
x=180/4
x=45 degrees= interior angle
So, exterior angle=3x=3(45)= 135 degrees.
