Cross multiply the expression so that we can get
(1+sinx)(1-sinx) = cos^2 x
1 - sin^2 x = cos^2 x
cos^2 x + sin^2 x = 1
since
cos^2 x + sin^2 x = 1
therefore
1 = 1
the two expressions are identical in a trigonometric sense

Answer:
42.40
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 49.88 × 15/100
