im not sure if this is correct but, i got C
Answer:




Solving for
we got
and replacing this we got:



And then the best option for this case would be:
b.csc x
Step-by-step explanation:
For this case we have the following expression given:

We know from math properties that the definition for cot is 
If we use this definition we got:


Now we can use the following identity:

Solving for
we got
and replacing this we got:



And then the best option for this case would be:
b.csc x
Answer:
log1/8
Step-by-step explanation:
Answer:
29
Step-by-step explanation:
AB+BC=AC
12+17=29=AC
Y = 4 x 2^-6
y = 4 x 1/2^6
y = 4 x 1/64
y = 1/16
