Given:

To find:
The exact value of cos 15°.
Solution:

Using half-angle identity:


Using the trigonometric identity: 

Let us first solve the fraction in the numerator.

Using fraction rule: 

Apply radical rule: ![\sqrt[n]{\frac{a}{b}}=\frac{\sqrt[n]{a}}{\sqrt[n]{b}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7B%5Cfrac%7Ba%7D%7Bb%7D%7D%3D%5Cfrac%7B%5Csqrt%5Bn%5D%7Ba%7D%7D%7B%5Csqrt%5Bn%5D%7Bb%7D%7D)

Answer:
10*7+ 18x *7 =2590
or 70 + 18x*7 =2590
Step-by-step explanation:
10*7 to find out how much the shipping costs for the 7 teams altogether
18*x because you need to find how much the jerseys cost for all the soccer teams
then multiply it by 7 to find how many players on each team
when you solve for x you get 20
there are 20 players on each on team.
