x represents one of the adjacent angles, so it can be either x or (x+30). Since the angles make up a 90° angle, the sum of the two angles must be 90°.
If x represents one of the angles, then the other angle would be (x+30).
Therefore, the equation would be: x + (x+30) = 90.
Simplifying the equation: 2x + 30 = 90.
Subtracting 30 from both sides: 2x = 60.
Dividing both sides by 2: x = 30.
So, the value of x is 30.
For two adjacent angles with measures x° and (x+30)° that make up a 90° angle, what is x ?(1 point)
