Answer:

The complement is 48 degrees.

Explanation:

Complementary angles add to 90 degrees.

angle = 90-42

angle = 48

The complement is 48 degrees.

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!
