The sum of the measures of the interior angles at vertex I and vertex J can be found by subtracting the measure of angle h from 180 degrees, since the angles at a vertex of a triangle add up to 180 degrees.
So, the sum of these interior angles is 180° - 142° = 38°.
Therefore, the correct answer is 38°.
