The equation would be y=3x+7
Csc²x - 1
1/sin²x - 1
1/sin²x - sin²x / sin²x
(1 - sin²x) / sin²x
Recall that sin²x + cos²x = 1
So cos²x = 1 - sin²x
So we can replace numerator to cos²x
cos²x / sin²x
= cot²x
Final answer: cot²x
Answer:
872
Step-by-step explanation:
Multiply 218 by 3, then add 218.
Answer:
D
Step-by-step explanation:
x=1
If a square contains 171 tiles you will need multiply 21 by 171 (171x21) which should give you the amount for the entire roof.
