If two angles make up a 90° angle, then they are complementary angles. This means that their measures sum up to 90°.
So we can set up the equation:
x + (x+30) = 90
2x + 30 = 90
Subtracting 30 from both sides:
2x = 60
Dividing both sides by 2:
x = 30
Therefore, x is 30°.
For two adjacent angles with measures%C2%A0 x° and (x+30)° that make up a 90° angle, what is x ?(1 point) Responses 15 15 20 20 30 30 60
