To find the equation to solve for x, we can use the fact that the sum of the measures of two angles is equal to 180 degrees.
So, the equation becomes:
mABC + mCBD = 180
135 + 9x = 180
Now, we can solve for x:
9x = 180 - 135
9x = 45
Dividing both sides by 9:
x = 5
Therefore, the equation to solve for x is 135 + 9x = 180, and the solution is x = 5.
two angles have measures that add to 180 degrees. They have the following angle measures m ABC=135 degrees and m CBD= 9x degrees. what is the equation to solve for x?
