Question

In right triangle ABC, where angle C is the right angle, sec B = sqrt117/9 Find csc A

Answer 1

Given:

$\sec \text{ B=}\frac{\sqrt[]{117}}{9}$$\begin{gathered} AC=\sqrt[]{117-81} \\ AC=\sqrt[]{36} \\ AC=6 \end{gathered}$$\begin{gathered} \csc A=\frac{AB}{BC} \\ \csc A=\frac{\sqrt[]{117}}{9} \end{gathered}$

Option A is the final answer
