    Let one angle be x Then the other angle will be x - 40. Since the 2 angles are complementary, x-40+x=90 2x=120 X=60. So the two angles can be 60 and 30. I hope it helps u mate :)

    We know that Two angles are complementary if the sum of their degree measures equals 90 degrees.

    x + y = 90     ----- (1).

    Given that Difference of two complementary angles is 40.

    x + y + x - y = 90 + 40

    2x = 130

    x = 65.

    Substitute x = 65 in (1), we get 

    x + y = 90

    65 + y = 90

    y = 25.

    The angles are 65 and 25.

    1Thank You
