Answer: Choice A) 45 + k*90
===================================
Work Shown:
2*tan(x) = 2*cot(x)
2*tan(x) = 2*(1/tan(x))
2*y = 2*(1/y) .... let y = tan(x)
2y = 2/y
2y^2 = 2
2y^2 - 2 = 0
2(y^2 - 1) = 0
y^2 - 1 = 0
(y+1)(y-1) = 0
y+1 = 0 or y-1 = 0
y = -1 or y = 1
tan(x) = -1 or tan(x) = 1
-------------
If tan(x) = -1 then x = 135 or x = 315
If tan(x) = 1, then x = 45 or x = 225
This is for 
In more general terms,
x = 45 + k*90
where k is an integer.
Answer:
D. D
Step-by-step explanation:
Where -1.9 is!!
The question states the : opposite of the opposite.
So- we find the opposite of (-1.9) =1.9 and the opposite of that is = -1.9.
So- it is situated at -1.9
Hope this helps!! =)
The answer is 48. This is because the opposite side which is 64 is just 32+32
Meaning k is 24+24
Raa that's hard but all I have to do is count how many chicken legs there r n then same w pigs
43. 9 + 10 + 13 + 13 = $45
45 - 1 = 44
44 x 4 = 176
176 + 8 = 184
184/4 = 46
46 tokens per person
44. a. 22 x 5 = 110
943/110 = 8.7
you will need 9 bookcases
b. 110 x 9 = 990
990 - 943 = 47
47 - 44 = 3
There will be 3 books on the third shelf.
