As we have learned

Results from General Solution -

\cos \Theta = 0 \Rightarrow \Theta = \left ( 2n+1 \right )\frac{\pi }{2}

-

 

 Since \theta = 10 \pi/ 2 = 5 \pi

 BUt \cos \theta = 0 \Rightarrow \theta = (2n+1)\pi /2

 


Option 1)

\theta = -3\pi /2

Option 2)

\theta =270 \degree

Option 3)

\theta = 300 \degree

Option 4)

\theta = 10\pi/ 2
