Complementary angles are two angles that add up to 90 degrees. Given the measures of the two angles as \( (2x)^\circ \) and \( (3x)^\circ \), we can set up the equation:

\[ 2x + 3x = 90 \]

Combining like terms gives:

\[ 5x = 90 \]

Now, solve for \( x \):

\[ x = \frac{90}{5} = 18 \]

Now that we have the value of \( x \), we can find the measures of the two angles.

For \( (2x)^\circ \):

\[ 2x = 2(18) = 36^\circ \]

For \( (3x)^\circ \):

\[ 3x = 3(18) = 54^\circ \]

Thus, the values are:

\[ x = 18, \quad (2x)^\circ = 36^\circ, \quad (3x)^\circ = 54^\circ \]
