\underline{\textbf{Given:}}

\mathsf{5\;cotA=8}

\underline{\textbf{To find:}}

\textsf{The value of sinA secA}

\underline{\textbf{Solution:}}

\mathsf{Consider,}

\mathsf{5\;cotA=8}

\implies\mathsf{\dfrac{1}{tanA}=\dfrac{8}{5}}

\implies\mathsf{tanA=\dfrac{5}{8}}

\mathsf{Now,}

\mathsf{sinA\;secA}

\mathsf{=sinA{\times}\dfrac{1}{cosA}}

\mathsf{=tanA}

\mathsf{=\dfrac{5}{8}}

\implies\boxed{\mathsf{sinA\;secA=\dfrac{5}{8}}}

⇒ 5 cot A = 8

⇒ cot A = 8/5

⇒ 1/tan A = 8/5

tan A = 5/8

Finding sinA secA

⇒ sin A • sec A

⇒ sin A • (1/cos A)

⇒ (sin A)/(cos A)

⇒ tan A

5/8

the value of sin A sec A is
