can someone help please

does anyone know how?

So first add 155 +80 +70 and you get 305. A polygon has interior angles that measure 540, so 540-305=235. Now divide that by 5 and get 47. That's x.

Wait sorry that has 4 sides. It should be equal to 360. So 155+80+70=305 360-305=55 x=11 Sorry for the previous mistake.
