We have to break each degree in terms of 90
A) 
Which is in third quadrant, therefore sine is negative hence
B) 
Which is in third quadrant, therefore cosine is negative hence
C) 
Which is in third quadrant, therefore tangent is positive hence
D) 
Which is in third quadrant, therefore cosec is negative hence
not defined
E)
Which is in third quadrant, therefore secant is negative hence
F) 
Which is in third quadrant, therefore tangent is positive hence
not defined
Hence only 
and
have value -1
Hope this will help
23 below zero means you will actually subtract (remove) 23 from zero.
This can be represented using the following expression:
0 - 23
To represent this as an integer, this means you will use a negative sign to represent the removal or subtraction of the number followed by the number removed which is 23, therefore:
The integer to represent this is -23.
It’s D I think. Since A and B are not random, C and E are not discrete
I got y=2/5x+31/5 as the answer
There are 16 oz. per 1 pound, so you have to multiply 21 by 16, which equals 336. Then you divide the 336 oz into 44 baskets. 336 / 44 = 7.64 oz
