Ratio = 1:3
or in other words = sale price:original price

Therefore, it'd look like this = sale price:$81
So to work out the original price, you'd do $81 divided by 3 (81 ÷ 3 = $27).

The sale price is $27..

Question 20: Please help what are sin x and cos x?
sweet [91]

Answer:

A is the correct answer.

Step-by-step explanation:

\tan x =   \frac{6}{8}  =  \frac{opposite \: side \: to \:  \angle \: x}{adjacent \: side \: to \:  \angle \: x}  \\  \\ hypotenuse  \\ =  \sqrt{ {(opp. \: side)}^{2} +  {(adj. \: side)}^{2}  }  \\  =  \sqrt{ {6}^{2} +  {8}^{2}  }  \\  =  \sqrt{36 + 64}  \\  =  \sqrt{100}  \\  = 10 \\  \\ \because  \sin (x) =  \frac{opposite \: side \: to \:  \angle \: x}{hypotenuse}  \\  \\   \huge{ \red{ \boxed{\therefore \: \sin (x) =  \frac{6}{10}}}}  \\  \\ \cos (x) =  \frac{adjacent \: side \: to \:  \angle \: x}{hypotenuse}  \\  \\  \huge{ \purple{ \boxed{\therefore \: \cos (x) =  \frac{8}{10} }}} \\

Thus, option A is the correct answer.
