Sec∅ = 1/cos∅
= 1/cos(240)
= 1/cos(180 + 60)
= 1/-cos(60)
= 1/(-1/2)
= -2

Answer:
He would need
cups of salt.
Step-by-step explanation:
We are given that,
The recipe requires
cups of flour and
teaspoons of salr.
As Nick wants to make the recipe using 1 cup.
Let the amount of salt needed = x
The ratio of the flour and salt will be same.
So, we have,
![\frac{\frac{3}{4}}{\frac{9}{8}}=\frac{1}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B3%7D%7B4%7D%7D%7B%5Cfrac%7B9%7D%7B8%7D%7D%3D%5Cfrac%7B1%7D%7Bx%7D)
i.e. ![\frac{3\times 8}{4\time 9}=\frac{1}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Ctimes%208%7D%7B4%5Ctime%209%7D%3D%5Cfrac%7B1%7D%7Bx%7D)
i.e. ![\frac{2}{3}=\frac{1}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7B1%7D%7Bx%7D)
i.e. ![x=\frac{3}{2}=1\frac{1}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B3%7D%7B2%7D%3D1%5Cfrac%7B1%7D%7B2%7D)
Thus, he would need
cups of salt if 1 cup of flour is used.
