Step-by-step explanation:

We can set up a proportion using fractions.

$\frac{4}{12} = \frac{28}{x}$

Now, let's cross multiply by multiplying 12 and 28 then dividing by 4.

$12\cdot28=336\\\\336\div4=84$

Hope this helped!

tan x = sin x/cos x

cos³ x *tan²x - cos x = cos³x *(sin²x/ cos² x) - cos= cosx*sin²x - cos x =

= cos x(sin² x - 1) = - cos x(1 - sin²x)= - cosx*cos²x = - cos³ x
