Answer 1

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**.
