This question is asking "Where does cosine equal
?"
Based on our unit circle values and the domain of the cos^{-1} function, we see that at 30 degrees, or
, cosine is equal to
.

The answer is C.
Answer:
m 7=129
Step-by-step explanation:
if 6 and 7 are right next to each other. it makes 180 degrees so you would take 180-51 to get your answer
Step-by-step explanation:
cot x / (1 + csc x)
Multiply by conjugate:
cot x / (1 + csc x) × (1 − csc x) / (1 − csc x)
Distribute the denominator:
cot x (1 − csc x) / (1 − csc²x)
Use Pythagorean identity:
cot x (1 − csc x) / (-cot²x)
Divide:
(csc x − 1) / cot x
To find the number of non-defective chips, we simply use this equation:
2,000 * 4/5
8000/5
Now you simply divide:
1600
1600 chips aren't defective
