For two adjacent angles with measures x° and (x + 30)° that make up a 90° angle, what is x?

Answer 1

The sum of two adjacent angles that make up a 90° angle is 90°.
So, we can write the equation x° + (x + 30)° = 90°.
Combining like terms, we have 2x + 30 = 90.
Subtracting 30 from both sides, we get 2x = 60.
Dividing both sides by 2, we find x = <<30=30>>30.
Therefore, x = 30.
