344.75 I did the math lol not that hard tbh
You would use the # line to add and subtract from Rose's total. The remaining amount that Rose still owes is $3.
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
