Let the measure of the angle be \( x \). The complement of the angle is \( 90 - x \).

According to the problem, the measure of the angle is 12 less than twice the measure of its complement. This can be expressed with the equation:

\[ x = 2(90 - x) - 12 \]

Now, let's solve for \( x \):

  1. Distribute on the right side: \[ x = 180 - 2x - 12 \] \[ x = 168 - 2x \]

  2. Now, add \( 2x \) to both sides: \[ x + 2x = 168 \] \[ 3x = 168 \]

  3. Divide both sides by 3: \[ x = \frac{168}{3} = 56 \]

The measure of the angle is \( 56 \).

Therefore, the correct response is 56.
