I will assume that the given values are the interior angles of a triangle
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
In this problem
x+(x+4)+6x=180
solve for x
8x+4=180
8x=180-4
8x=176
x=22 degrees
so
X+4=22+4=26 degrees
6x=6(22)=132 degrees
therefore
the interior angles are
x=22 degrees
x+4=26 degrees
6x=132 degrees
