x=19 * sin(40)

x = 12.21

1) Since we have a right triangle and the opposite leg to angle 40ยบ, then we can write the following trig ratio


\begin{gathered} \sin (40)=(x)/(19) \\ x=19\cdot\sin (40) \\ x=12.21296 \\ x\approx12.21 \end{gathered}

2) Then the equation for that is x= 19*sin(40) and the value of that leg is approximately 12.21 units
