Ernesto · Answer 1

Complementary angles measures to the sum of 90 degrees. Since there is already an angle of 42 degrees, simply subtract 90 from 42, and you get 48 degrees ...

angle A + angle B = 90 degrees, so

42 + x=90

x=48

Lamar Wells · Answer 2

Complementary angles add up to 90 degrees.

So we can write:

42 + x = 90

To solve, subtract 42 to both sides:

x = 48

So the complement of a 42 degree angle is a 48 degree angle.
