Answer:
A and C
Step-by-step explanation:
<h3>A</h3>

<h3>C</h3>

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
If from the negative to the positive side, count how many dots are in between and add together. So it is 6 units apart or 6 dots apart.
