a. The equation for these two supplementary angles can be written as:
180 - x = x + 60
b. To solve for the value of x, we can set up and solve the equation:
180 - x = x + 60
Combine like terms:
180 = 2x + 60
Subtract 60 from both sides:
120 = 2x
Divide both sides by 2:
60 = x
c. To find the measurement of each angle, we substitute the value of x into the equation:
180 - x = 180 - 60 = 120
x + 60 = 60 + 60 = 120
The measurement of each angle is 120 degrees.

a. The equation for these two supplementary angles can be written as:
2x + 3 = 180 - (x - 6)
b. To solve for the value of x, we can simplify and solve the equation:
2x + 3 = 180 - x + 6
Combine like terms:
2x + 3 = 186 - x
Add x to both sides:
3x + 3 = 186
Subtract 3 from both sides:
3x = 183
Divide both sides by 3:
x = 61
c. To find the measurement of each angle, we substitute the value of x into the equations:
2x + 3 = 2(61) + 3 = 122 + 3 = 125 degrees
x - 6 = 61 - 6 = 55 degrees
The measurement of the angle on the left is 125 degrees, and the measurement of the angle on the right is 55 degrees.
