The sum of the inside angles of a triangle, always sum up to 180 degrees. Using this information, we can create the following equation for this problem:

Adding up all terms with 'x' and adding the other together, we have the following equation:

Solving this last equation for 'x', we have the following:

Then, the final answer for the 'x' value is twelve!
