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 :

$(rope)/( \sin(50) ) = (25.17)/( \sin(40) ) \\$

$(rope)/( \cos(40) ) = (25.17)/(0.643) \\$

$(rope)/(0.766) = (25.17)/(0.643) \\$

rope = 0.766 * (25.17)/(0.643)

rope = 0.766 * 39.14

rope = 30.37

rope = 30

And we're done...
