Answer 1

To solve for \( x \) in the problem where two adjacent angles measure \( x^\circ \) and \( (x + 30)^\circ \) that form a 90° angle, you can set up the following equation:

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

Combine like terms:

\[
2x + 30 = 90
\]

Subtract 30 from both sides:

\[
2x = 60
\]

Divide by 2:

\[
x = 30
\]

So the value of \( x \) is \( 30 \).

Thus, the correct response is:

30
