We can write a proportion to solve

14         10

------ = ------

21          x

Using cross products

14x = 21*10

14x =210

Divide each side by 14

14x/14 = 210/14

x =15

Find the exact value by using a half-angle identity. . cos(5π/12).
vodka [1.7K]
<span>First of all in order to find the exact value by using a half angle identity we will do
cos(5π divided by 12)

=cos (5π divided by 6) divided by 2
= ± Under root[(1+cos (5π divided by 6) divided by 2]
Now we will consider + sign because 5π divided by 12 is in quadrant. where cos>0
so the solution is [(1- Under root 3 divided by 2) divided by 2] 
We will ignore the negative sign
I hope it helped.</span>
