To find the value of x, we need to set up an equation based on the given information.

Since the two angles are adjacent and make up a 90° angle, their sum should be 90°.

Therefore, we have:

x + (x+30) = 90

Simplifying the equation, we get:

2x + 30 = 90

Subtracting 30 from both sides, we have:

2x = 60

Finally, dividing both sides by 2, we find:

x = 30

So the value of x is 30°.
