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?
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.
