Answer:
12.5663706144
If necessary, and if your system/teacher allows it, just keep it down to 1-3 decimals.
Hope I could help! :D
Step-by-step explanation:
L.H.S=(1-cosB)(1+cosB)
=(1-cos^2B). {using (a+b) (a-b)=(a^2-b^2)in second step}
=sin^2B
=1/cosec^2B
Therefore,L.H.S=R.H.S proved
(2,3) , (0,-3) , (-2,1) are the points.
Hope this helps... Let me know if you wanna know anything.
