It is a speacial right triangle. It always has 30,60, or 90 degrees.
y = 316
because 98 times 3 equals 294. Then add 22 and your whole answer is
y = 316.
You get the mean by finding the middle term if its an odd number if its an even number get the 2 middle numbers add thema nd divide them by 2 in this case the answer would be 9
Hope this helps
