Answer:
Third option is the right choice.
Step-by-step explanation:
Manipulate the right hand side.

sin ^2 (x)+ cos^2(x) = 1
sin ^2 (x)+ cos^2(x)
------------------------
cos (x)
We know that sin ^2 (x)+ cos^2(x) = 1
1
The definition of sec is 1 /cos
= sec(x)
Slope is 3
2/3 x + 1 = 27
subtract 1 from each side
2/3 x = 26
multiply by 3/2
3/2 * 2/3 x = 26 * 3/2
x = 39
3 + 6 = 1/2(#grapes)
3 + 6 = 9
9 = 1/2(#grapes)
2(9) = 1(#grapes)
18 = # of grapes
62+78=140
360-140=220
220÷2=110
