1) expand csc and cotx identity
(1/sinx)-sinx = (cosx/sinx)*(cosx)
2) get common denominator on the left side
(1-sin^2x)/(sinx)= (cos^2x)/sinx
3) using cos^2x+sin^2x=1 you finished
cos^2(x)/sinx= cos^2(x)/sinx

Answer:
The answer is 64.29% hope it helps
The original price was 100% and the sale was -25%
100% - 25% = 75%
This means 75% = £33
75% = 3/4
If we divide the sale amount by 3 and them multiply by 4, we will get the original amount.
£33 / 3 = £11
£11 x 4 = £44
