Ahat [919]

Step-by-step explanation:

Let the marked price of a watch be =₹x

∴ Discount price = x- 20% of x

= x - 0.2x

=0.8x

Amount of VAT = 13% of 0.8x

0.13 x 0.8x

0.104x

Now,

Selling price = 0.8x + 0.104x

∴6328 = 0.904x

x = 0.904 / 6328

x=0.00014285714

Write the expression as either the sine, cosine, or tangent of a single angle. tan5x - tan2y / 1 + tan5x tan2y

Kryger [21]

$\bf \textit{Sum and Difference Identities}
\\\\
tan(\alpha + \beta) = \cfrac{tan(\alpha)+ tan(\beta)}{1- tan(\alpha)tan(\beta)}
\qquad
tan(\alpha - \beta) = \cfrac{tan(\alpha)- tan(\beta)}{1+ tan(\alpha)tan(\beta)}\\\\
-------------------------------\\\\
\cfrac{tan(5x)-tan(2y)}{1+tan(5x)tan(2y)}\implies tan(5x-2y)$
