Step-by-step explanation:

We know that cosx = sin( $\pi$ - x)

We can apply it here:

sin(55°) = cosx

cos( $\pi$ - 55°) = cosx

Now we apply the arccos to both sides:

x = $\pi$ - 55° + 2k $\pi$ or x = - $\pi$ - 55° + 2k $\pi$

The value of $(\frac{f}{g})(5)$ is $\frac{27}{35}$

Explanation:

Given that f(x)=7+4x and g(x)=7x

The value of $(\frac{f}{g})(5)$ :

The value of $(\frac{f}{g})(5)$ can be determined by substituting x = 5 in the functions f(x) and g(x) and then dividing the terms, we get, the value of $(\frac{f}{g})(5)$

Thus, we have,

$(\frac{f}{g})(5)=\frac{f(5)}{g(5)}$
