    Complementary angles are 2 angles that sum up to 90 degrees.

    We can solve this two ways.

    Solution 1:

    Subtract.

    90 - 42 = 48 degrees.

    Solution 2:

    42 + x = 90

    Subtract 42 to both sides

    42 - 42 + x = 90 - 42

    Simplify

    x = 48 degrees

    Best if Luck!

    48

    Step-by-step explanation:

    Complementary angles add to 90 degrees

    Let x be the unknown angle

    x+42 = 90

    Subtract 42 from each side

    x+42-42 = 90-42

    x = 48

    The complement is 48 degrees
