The sum of the two adjacent angles that make up a 90° angle must equal 90°.
Therefore, we have the equation:
x + (x + 30) = 90
By simplifying the equation, we get:
2x + 30 = 90
Then, subtracting 30 from both sides:
2x = 60
Finally, dividing both sides by 2:
x = 30
Therefore, x = 30.
for two adjacent angles with measures x° and (x+30)° that make up a 90° angle, what is x ?(1 point) responses 20 20 60 60 15 15 30
