Answer:
-3,694
I am not sure what in the world the rest means, so I am very sorry. I just subtracted some stuff. I have no clue if that helped...
1 / cos^2 O - 3 / cos O - 2 = 0
1 - 3 cos O - 2 cos^2 O = 0
2 cos^2 O + 3 cos O - 1 = 0
cos O = 0.2807 , -1.78 ( -1.78 cannot be a solution)
O = 74 degrees (from 0.2807) another solution is 360-74 = 286 degrees
Its D
Given:
Consider the below figure attached with this question.
The table represents a proportional relationship.
To find:
The missing value from the table.
Solution:
If y is proportional to x, then

...(i)
Where, k is a constant of proportionality.
The relationship passes through the point (-3,-1). Substituting
in (i), we get



Putting
in (i), we get
...(ii)
We need to find the y-value for
.
Substituting
in (ii), we get


Therefore, the missing value in the table is -4. Hence, option D is correct.
