1 ) cot x * sin x = cos x
(cos x / sin x) * sin x = cos x
cos x = cos x
Answer: B ) cot x = cos x / sin x
2 ) ( sin² x + cos² x ) / cos x = sec x
1/cos x = sec x
sec x = sec x
Answer: C ) cos² x + sin² x = 1
Answer:
The total amount of ribbon she had was 35 feet of ribbon.
Step-by-step explanation:
I hope this is one of the answers and I hope this helps you. Stay safe:)
She is correct.
