What is the value of x knowing that the interior angle of this regular polygon is (-134x+516+2x)?

well, if there are only three angles, then you have a triangle, and they add up to 180 degrees.

To find the value of x for the given regular polygon, we need to set the interior angle equal to the sum of the interior angles of a regular polygon.

The sum of the interior angles of a regular polygon with n sides is given by the formula: (n - 2) * 180 degrees.

So, we have the equation: (-134x + 516 + 2x) = (n - 2) * 180 degrees.

To solve for x, we need more information about the polygon, specifically the number of sides (n).
