In that image you had posted in the screenshot website, I didn't see any "C", but if you want to find the value of "x", you would add up all the angles of the triangle and then set them equal to 180, since 180 is what all angles of a triangle always equal to.
Like this: x + 6x+10 + x+2 = 180
THen you just use Algebra to solve! If you're looking for a specific angle measure, then you'd use that "x" value you found from the above equation and then you'd plug it into any angle expression and solve!
Hope this helps, hoiuu!
