ycow [4]

Step-by-step explanation:

sin  x \: cos  x \: tanx = 1 -  {cos}^{2} x \\ LHS \\= sin  x \: cos  x \: tanx \\  =sin  x \: cos  x \: \times  \frac{sin  x}{cos  x}  \\  = sin  x \: \times  \frac{sin  x}{1} \\  ={sin}^{2}  x \\  = 1 -  {cos}^{2} x \\  = RHS \\  \therefore \: sin  x \: cos  x \: tanx = 1 -  {cos}^{2} x \\ Hence \: Proved.

A sweater is on sale for 20%
bagirrra123 [75]
 $72 To find out how much the sweater is without 20% off, you need to do this formula:

$60 x 20%

The answer is $12.

So, 20% of $60 is $12.

Now, you need to add 60 and 12 together to get the original sale price.

60 + 12

The answer is 72.

So the original price for the sweater is <span>72 dollars.</span>
