Answer 1

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°.
