To find the value of x, we need to set up the equation for the sum of the two adjacent angles equal to 90°:
x + (x+30) = 90
Simplifying the equation, we get:
2x + 30 = 90
Subtracting 30 from both sides of the equation, we have:
2x = 60
Dividing both sides by 2, we find:
x = 30
Therefore, x is equal to 30°.
