Answer:
Acute angle
Step-by-step explanation:
Given that m<C = 
, to find out the type of angle angle C is, evaluate the expression given by substituting x = 13, in the expression.
m<C =
m<C = 
m<C = 
m<C = 76°
Acute angles are less than 90°.
m<C is less than 90°, therefore it is an acute angle.

Step-by-step explanation:
Answer:
2x^2 +11
Step-by-step explanation:
f(x) = 3x^2 +2
g(x) = x^2 -9
f(x) - g(x) = 3x^2 +2 - (x^2 -9)
Distribute the minus sign
= 3x^2 +2 -x^2 +9
Combine like terms
= 2x^2 +11
