" Evaluate ":(96sin65^(@)sin35^(@)sin80^(@))/(sin20^(@)+2sin80^(@)cos30^(@))

Evaluate: (96 sin 65^(@) sin35^(@) sin80^(@))/(sin20^(@) + 2 sin 80^(@) cos30^@)

sin20^(@)sin40^(@)sin60^(@)sin80^(@)

sin20^(@)+sin40^(@)-sin80^(@)=

sin10^(@)+sin20^(@)+sin40^(@)+sin50^(@)=sin70^(@)+sin80^(@)

The exact value of (96sin80^(@)sin65^(@)sin35^(@))/(sin20^(@)+s in50^(0)+s in110^(0)) is equal to 12 (b) 24(c)-12 (d) 48

Find sin20^(@)sin40^(@)sin60^(@)sin80^(@) .

sin10^(@)+sin20^(@)+sin40^(@)+sin50^(@)-sin70^(@)-sin80^(@)=

sin 20^(@) sin 40^(@) sin 60^(@) sin 80^(@) =(3)/(16)

Show that sin10^(@)+sin20^(@)+sin40^(@)+sin50^(@) =sin70^(@)+sin80^(@)
