What is the equation for determining the angle measures (7x - 9) and 4x?
To determine the angle measures, we need to set the two angles equal to each other and solve for x.
(7x - 9) = 4x
Now, we can solve for x by subtracting 4x from both sides:
7x - 9 = 4x
3x - 9 = 0
3x = 9
x = 3
Now that we have found the value of x, we can substitute it back into the equations to find the angles:
Angle 1 = 7x - 9 = 7(3) - 9 = 21 - 9 = 12 degrees
Angle 2 = 4x = 4(3) = 12 degrees
Therefore, the angle measures are 12 degrees and 12 degrees.
