\sin \,\,{\theta _1} + \sin \,\,{\theta _2} + \sin \,\,{\theta _3} = 3

, then

\cos \,\,{\theta _1} + \cos \,\,{\theta _2} + \cos \,\,{\theta _3} =

View answer and explanation

Correct option: D

\mathrm{0}

Option D (0) is correct because the maximum value of

\sin \theta

is 1, which implies

\theta_1 = \theta_2 = \theta_3 = \frac{\pi}{2}

, making the sum of cosines zero.
