If sin theta _1+ sin theta _2+ sin theta _3=3 " then " cos theta _1 + cos theta _2 + cos theta_3 =

If sin theta_(1)+sin theta_(2)+sin theta_(3)=3 then cos theta_(1)+cos theta_(2)+cos theta_(3)=

If sin theta_(1)+sin theta_(2)+sin theta_(3)=3, then cos theta_(1)+cos theta_(2)+cos theta_(3) is equal to 3(b)2(c)1(d)0

If sin theta_1 + sintheta_2 + sin theta_3 = 3 then find the value of cos theta_1 + cos theta_2 + cos theta_3.

If sin theta_1 + sintheta_2 + sin theta_3=3, then find the value of cos theta_1 + cos theta_2 + cos theta_3.

If sin theta_1 + sintheta_2 + sin theta_3 = 3 then find the value of cos theta_1 + cos theta_2 + cos theta_3.

If Sin theta_(1) + Sin theta_(2) + Sin theta_(3) = 3 then Cos theta_(1) + Cos theta_(2) + Cos theta_(3) =
