How would I solve for x attached circle? We cannot assume XW is a diameter because it was not given in this problem. Can x be found with the given info?

You're not getting any help if you're not CLEARER! Is 8x + 12 = line XY or arc XY? (similarly with YW) Is 8x + 4 = angle XYW?

8x+4 is the inscribed angle. I figured it out by multiply 2(8x+4). Then I added all three known arc lengths and set them equal to 360 and solved for x = 11.
