70+70= 140 points gained minus 145 points lost or 140 - 145= -5 points.
In the smallest of the three triangles (with sides 
) we have
In the second-largest triangle (with sides 
), the length of the missing side is 
. Then in the largest triangle (with sides 
), we have
Equivalently, we have
In turn, we find
Ok, think of 16.4 as 16.40 and 16.5 as 16.50
so between 40 and 50 there are lots of numbers
pick any three
Ex: 16.42, 16.49, 16.45
Well, when you say which pair, I would expect that there would be some choices to choose from... if it is one of the choices, I would go with
