Both the interior and the exterior angle of the triangle must equal 180 degrees.
The interior angle is half of what the exterior angle is which must mean that the exterior angle is 120 degrees and the interior angle is 60 degrees (only way of solving this equation).
The two other angles inside the triangle added with the interior angle that is 60 degree must equal 180 degrees. Therefore the sum of these two angles must equal 120 degrees.
