to find the range of a set of numbers, first put the numbers in order from smallest to largest (which is already done) and simply subtract the smallest number from the biggest one!
the smallest being 45 and the highest is 92 in this case! hope this helps
These shapes are geometric, which means they're equal. XW would be the same as XY, which is 18. The same goes towards WZ. WZ = ZY, so it'll be 29. Remember, since it's geometric, each side has to equal each other
