Let the two remaining angles be x and 2x.
Since the sum of all angles in a pentagon is 540 degrees, we can set up the equation:
90 + 120 + 140 + x + 2x = 540
Simplifying, we get:
350 + 3x = 540
3x = 190
x = 63.33 degrees
Therefore, the two remaining angles are 63.33 degrees and 2(63.33) = 126.67 degrees.
