<span>75.4615 is the answer I got. hope this helped let me know if the answer is correct </span>
(csc x-1)(csc x+1)=csc²x-1²=csc²x-1=(1/sin x)² -1=1/sin x² - sin²x/sin²x=
=(1-sin²x)/sin² x = cos² x/ sin² x = (cos x/sin x)²= (cot x)²
Answer:
B
Step-by-step explanation:
Answer:
D. b=7a
Step-by-step explanation:
Add -11/3a to both sides.

Divide both sides by 1/3
1
