To find the value of \( x \) for the two adjacent angles that add up to \( 90^\circ \), we can set up the equation based on the information given.

The first angle is \( x \) degrees, and the second angle is \( (x + 30) \) degrees. Since these two angles are complementary (they add up to \( 90^\circ \)), we can write the equation:

\[
x + (x + 30) = 90
\]

Now, simplify the equation:

\[
x + x + 30 = 90
\]

Combine like terms:

\[
2x + 30 = 90
\]

Next, subtract 30 from both sides:

\[
2x = 90 - 30
\]

\[
2x = 60
\]

Now, divide both sides by 2:

\[
x = \frac{60}{2}
\]

\[
x = 30
\]

So, the measure of the angle \( x \) is \( 30^\circ \).
