k=[sin(54)/( $\sqrt{sin126}$+ $\sqrt{\(sin54)(sin36)}$ )]
You asked:
Solve the equation \(k = \frac{\sin\left( 54 \right)}{\sqrt{\sin\left( 126 \right)} + \sqrt{\sin\left( 54 \right) \cdot \sin\left( 36 \right)}}\) for the variable \(k\).
MathBot Answer:
The solution is: \[k = \frac{\sin{\left(54 \right)}}{\sqrt{\sin{\left(126 \right)}} + \sqrt{- \sin{\left(36 \right)}} \sqrt{- \sin{\left(54 \right)}}} \approx -0.42368095\]
