Answer:
The value will be 56
Step-by-step explanation:
We have given polynomial 
We have to find P(-2)
For finding P(-2) we have to put x = -2 in the polynomial
So P(-2) = 
So value of P(-2) will be 56
For finding any value we have to just put that value in the polynomial
Answer:
C
Step-by-step explanation:
Both segments AC and BC intersect at point C. Hence, the angle included by them will be angle C.
