    52.5 degrees and 82.5 degrees

    Step-by-step explanation:

    In this question, we want to calculate the measures of the other interior angle of a triangle given those ratio

    Mathematically, the total angle present in a triangle is 180 degrees. we have the value of one of the angles, this means that the other two will sum up to be 180 - 40 = 140 degrees

    Now we know that the remaining two angles are in the ratio 3:5; we shall now split these into two based on their ratios.

    That would be 3/8 * 140 and 5/8 * 140

    3/8 * 140 = 3 * 17.5 = 52.5

    5/8 * 140 = 5 * 17.5 = 87.5
