The measure of the angle x is 125 degrees
The sum of the interior angle of the given polygon is 720 degrees
Take the sum of the interior angles;
120+100+x+120+120+x+10 =720
Simplify to have;
340+130+2x = 720
470+2x = 720
2x
2x = 720-470
2x=250
x =125 degrees
Hence the measure of the angle x is 125 degrees
