For two adjacent angles with measures x° and (x+30)° that make up a 90° angle, what is x ?(1 point)
If two angles are adjacent and make up a 90° angle, then they are complementary angles. In other words, the sum of their measures is 90°.
So, we have the equation:
x + (x + 30) = 90
Simplifying, we have:
2x + 30 = 90
Subtracting 30 from both sides:
2x = 60
Dividing both sides by 2:
x = 30
Therefore, x is equal to 30°.
