what is the measure of angle x?

All the interior angles of a triangle must add up to 180 degrees.
This means that the sum of x, 102, and 31 must equal 180.




Subtract both sides by 133




The measure of x is 47 degrees. You can verify this by adding all the interior angles. I hope this helps! :)
