Applying the trigonometric ratios, the equations that can be used are:

sin 45 = BC/9

cos 45 = BC/9

<h3>How to Apply the Trigonometric Ratio?</h3>

In the given image below, to find the unknown lengths of the triangle, we would apply the following trigonometric ratios:

To find AC, use the cosine ratio, CAH.

To find BC, use the sine ratio, SOH.

sin 45 = opp/hyp = BC/9

sin 45 = BC/9

cos 45 = adj/hyp = BC/9

cos 45 = BC/9

You increase the size of a computer screen display by 20%. Then you decrease it by 20%. What is the size of the computer screen
lutik1710 [3]

Answer: The size of computer display after 20 % increase and then 20 % decrease= 96 % of the original size.


Step-by-step explanation:

Let the original size of computer be 100x , then if it increases by 20 %

then the new size of the computer=100x +20% of 100x

=100x+\frac{20}{100}\times100x\\=100x+20x\\=120x

The size of computer after 20% increase= 120x

If size of computer is decreased by 20 % then

The new size of computer= 120x - 20% of 120 x

=120x-\frac{20}{100}\times120x\\=120x-24x\\=96x

On comparing it to the original size , we get

\frac{96x}{100x}\times100=96\%

Thus, the size of computer display after 20 % increase and then 20 % decrease= 96 % of the original size.
