Let's  find the point (P) of attachment....we have that

 

sin (36°)    =   P  / 60    multiply both sides  by  60

 

60sin (36°)  = P

 

So....in the second situation we have  that

 

sin (new angle)    = 60sin(36°) /  110

 

sin (new angle)  =  6sin (sin 36°)  /11

 

Take the arcsin

 

arsin  [ 6 sin (36°) / 11]   =  new angle ≈  18.7°

 

LOOKS GOOD, JENNY     !!!!!

 

 

cool cool cool
