dock = 90°
boat = 40°
Thus the other angle equal 50°
I call that angle JJ
So ; JJ = 50°
_________________________________
According to the case of the Sine :
[tex] \frac{rope}{ \sin(50) } = \frac{25.17}{ \sin(40) } \\ [/tex]
[tex] \frac{rope}{ \cos(40) } = \frac{25.17}{0.643} \\ [/tex]
[tex] \frac{rope}{0.766} = \frac{25.17}{0.643} \\ [/tex]
[tex]rope = 0.766 \times \frac{25.17}{0.643} [/tex]
[tex]rope = 0.766 \times 39.14[/tex]
[tex]rope = 30.37[/tex]
[tex]rope = 30[/tex]
And we're done...
