a, b, c - side lengths (a ≤ b ≤ c)
If 
, then is Obtuse triangle.
If 
, then is Right triangle.
If 
, then Acute triangle.
Check to see if the sum of the first two sides is greater than the third.
, therefore is Scalene triangle.

divide the total tax by the rate
8.75% = 0.0875
4.59/.0875 = 52.457 round to 52.46
So M=Mabels score
N=Nancys score
P=Phoebes score
M=N+19
P=N-10
p=23 Therefore Nancys Score is 33
Mabel scored 19 more points on her test than Nancy did.
So therefore add N+M = 52
