3 \sin ^2 \theta+2 \sin ^2 \phi=1

and

3 \sin 2 \theta=2 \sin 2 \phi, 0 < \theta < \frac{\pi}{2}

and

0 < \phi < \frac{\pi}{2}

, then the value of

\theta+2 \phi

View answer and explanation

Correct option: A

\frac{\pi}{2}

Option A (

\frac{\pi}{2}

) is correct because after simplification and using trigonometric identities,

\theta + 2\phi

equals

\frac{\pi}{2}
