The value of
sin100.sin120.sin140.sin160 is
0.1875

Explanation:

To find the value of
sin100.sin120.sin140.sin160, let us find the value of each angle.

The value of
sin100=0.9848

The value of
sin120=(√(3) )/(2)

The value of
sin140=0.6428

The value of
sin160=0.3420

Substituting the values of sin, we get,


sin100.sin120.sin140.sin160=0.9848*(√(3) )/(2) *0.6428*0.3420

Multiplying the values of sin, we get,


sin100.sin120.sin140.sin160=0.1875

Thus, the value of
sin100.sin120.sin140.sin160 is
0.1875
