Question

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?

Answer 1

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.
