If two adjacent angles make up a 90° angle, then their sum must be equal to 90°.
So, we can set up the following 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
Therefore, x is equal to 30°.
For two adjacent angles with measures x° and (x+30)° that make up a 90° angle, what is x ?(1 point)
