Answer:
Well where do you start
Step-by-step explanation:
Both terms have a

in common, so we can pull it out. The factored form will be

times whatever is left after pulling it out.
In the first term, we will have just 8 left since everything else in the term is factored out.
The second term has a

left. Notice that both of these terms no longer have a negative sign since the negative was factored out.
The answer is
Answer: 10
Step-by-step explanation: We can just count the number of vertices in the star and each vertex makes an angle. There are ten vertices in a star and thus ten angles.
Sin 30 = 16/x
x = 16/sin 30 = 32
The answer is d: 32.
