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=(AB)/(BC) \\ \csc A=\frac{\sqrt[]{117}}{9} \end{gathered}`

Option A is the final answer
