To form a right angle, the sum of the two adjacent angles must be 90 degrees.
So we can set up the equation:
x + (x + 30) = 90
Combining like terms:
2x + 30 = 90
Subtracting 30 from both sides:
2x = 60
Dividing both sides by 2:
x = 30
Therefore, the two angle measures are 30° and 30° + 30° = 60°.
A right angle is formed by two adjacent angles with measures of (x)° and (x+30)° . What are the two angle measures?(1 point)
