k=[sin(54)/( $\sqrt{sin126}$+ $\sqrt{\(sin54)(sin36)}$ )]^{2}
You asked:
Solve the equation \(k = {\left( \frac{\sin\left( 54 \right)}{\sqrt{\sin\left( 126 \right)} + \sqrt{\sin\left( 54 \right) \cdot \sin\left( 36 \right)}} \right)}^{2}\) for the variable \(k\).
MathBot Answer:
The solution is: \[k = \frac{\sin^{2}{\left(54 \right)}}{\left(\sqrt{\sin{\left(126 \right)}} + \sqrt{- \sin{\left(36 \right)}} \sqrt{- \sin{\left(54 \right)}}\right)^{2}} \approx 0.17950555\]
