Question

7/9-12/45 what is answer​

Answer 1

Step-by-step explanation:

We Know that,

\begin{gathered}\large \bf \red\bigstar \: \: \orange{ \underbrace{ \underline{sec A = \frac{1}{cosA} }}} \\ \end{gathered}

★

sec A=

cosA

1

Hence,

\begin{gathered}:\longmapsto \rm secA = \frac{1}{8/17} \\ \end{gathered}

:⟼secA=

8/17

1

\begin{gathered}\purple{ \large :\longmapsto \underline {\boxed{{\bf sinA = \frac{17}{8} } }}} \\ \end{gathered}

:⟼

sinA=

8

17
