Answer:
check it..
Step-by-step explanation:
domain and range...
The Law of Cosines would be your best bet here, since the unknown side is opposite the known angle 110 degrees.
|AC|^2 = (8 in)^2 + (23 in)^2 - 2(8 in)(23 in)*cos 110 degrees
= 64 in^2 + 529 in^2 - (368 in^2)*(-0.342)
= 593 in^2 + 126 in ^2 approximately
= 719 in^2 approximately
Then the length of side AC is approx. √(716 in^2) = 27 in
Answer:

Step-by-step explanation)
n(3) - 5 = 7
n(3)= 7 + 5
n(3)= 12
n3/3 = 12/3
n =4
