Final answer:
To determine the value of x, set the measure of the angle equal to 360 degrees and solve for x.
Step-by-step explanation:
To determine the value of x, we need to set the measure of the angle equal to 360 degrees since the sum of the interior angles of a polygon is always 360 degrees. So we have:
8x - 48 = 360
Adding 48 to both sides:
8x = 408
Dividing both sides by 8:
x = 51
Therefore, the value of x is 51. None of the given options accurately represent the value of x, so the correct answer is not listed.
