_______________

Cosine and secant functions are reciprocal, which means

$\mathsf{sec\,\theta=\dfrac{1}{cos\,\theta}}$

So, if $\mathsf{cos\,\theta=\dfrac{3}{8},}$ then

$\mathsf{sec\,\theta=\dfrac{1}{~\frac{3}{8}~}}\\\\\\
\mathsf{sec\,\theta=\dfrac{8}{3}\qquad\quad\checkmark}$

I hope this helps. =)
