Answer:
and 
Step-by-step explanation:
To solve this, you must set up a system of equations. The first sentence says that there are two numbers and that their sum is 91, so your first equation is 
. For the next equation, it says that the difference of those same numbers is 1, which means that the equation is 
. Now, putting those two together for the system of equations, it's easiest to add them. The result will be 
which when simplified gives you the value of x. Taking the value of x, you can substitute in the second equation to find the value of y.
Hope this helped!
so.. to get every angle, simply plug in 10 for "x" for each.
He is correct and incorrect. 2 and 4 can create factors but they can also be factors of other numbers. So 8 can be a factor of bigger whole numbers and can also have it own smaller factors.
