To find the value of x, we can use the fact that the sum of the measures of two adjacent angles that form a straight line (180°) is 180°. Since the two angles in question make up a 90° angle, their measures should add up to 90°.

Therefore, we can write the equation:

x + (x + 30) = 90

Simplifying the equation, we get:

2x + 30 = 90

Subtracting 30 from both sides, we have:

2x = 60

Dividing both sides by 2, we get:

x = 30

Therefore, the value of x is 30°.
