Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
• 1 + cot²x = csc²x
Consider the left side
x - 
x
Factorise as a difference of squares
= (csc²x - cot²x)(csc²x + cot²x)
= (1 + cot²x - cot²x)(csc²x + cot²x)
= csc²x + cot²x
= csc²x + csc²x - 1
= 2csc²x - 1 = right side ⇒ verified
7 and 1/2 mile because 2,640=1.5 miles
4-1.5=2.5+5=7.5
Answer:
the answer is 33
Step-by-step explanation:
because 800 divided by 24 equals. 33
629,999 =630,000. Nearest hundred
Answer:
80
Explanation:
