Distribution property
a(b+c) = ab*ac
now, why does this matter
cause
-(9-10n) is equivalent to -1*(9-10n)
applying distribution property
-1*(9-10n) = -1*9 +-1-10n= -9 +10n
Answer:
Obtuse.
Step-by-step explanation:
If sides are a b and c, with c the longest:
c^2 = a^2 + b^2 = Right triangle
c^2 < a^2 + b^2 = Acute ...
c^2 > a^2 + b^2 = Obtuse ...
33^2 = 1089
25^2 = 625
9^2 = 81
625 + 81 = 706
1089 > 706 so the triangle is obtuse.

pretty sure its,100
