Since $\sin 	heta_{1}+\sin 	heta_{2}+\sin 	heta_{3}=3$

$	herefore \quad \sin 	heta_{1}=\sin 	heta_{2}=\sin 	heta_{3}=1$

$\Rightarrow \quad 	heta_{1}=	heta_{2}=	heta_{3}=\frac{\pi}{2}$

$ 	herefore \quad \cos 	heta_{1}=\cos 	heta_{2}=\cos 	heta_{3}=0 $

$ 	herefore \quad \cos 	heta_{1} =\cos 	heta_{2}=\cos 	heta_{3}=0 $

If $sin\theta_1 + sin\theta_2 + sin\theta_3 = 3,$ then $cos\theta_1 + cos\theta_2 + cos\theta_3=$
