I have to find the variable but is it 20/7= 24/x or 24/20= 7/x
harkovskaia [24]
It can actually be done many ways. You must match up the corresponding sides.

For example, 24/20 and x/7 would work so would, 24/x and 20/7, and 7/20 and x/24. Most proportions are set up the same way. You just have to make sure to go in the same order for the two triangles. Sorry if it's confusing.

So let's use-20/7 and 24/x.

First, we multiply 7*24 and 20*x and we get 20x=168

Then we divide to get 168/20. X=8.4

Find the value of x.pls. ​
Crank

Answer:

x = 13\sqrt{2}

Step-by-step explanation:

Using the sine ratio with the 45° angle on lower left and the exact value

sin45° = \frac{1}{\sqrt{2} }

ain45° = \frac{opposite}{hypotenuse} = \frac{13}{x} = \frac{1}{\sqrt{2} } ( cross- multiply )

x = 13\sqrt{2}

The median for the given set of six ordered data values is 27. 5. 9 12 23 ​_ 41 48 What is the missing​ value?
Korvikt [17]

Considering the median, the missing value of the data-set is of 31.

<h3>What is the median of a data-set?</h3>

The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.

In this problem, since the set has even cardinality, the median is the mean of the middle elements, which are 23 and x. Since it is of 27, we have that:

(23 + x)/2 = 27

23 + x = 54

x = 31

Hence, the missing value of the data-set is of 31.

Prove the identity<br> (cot x sin x)(sec x – cos x) = sin^2x
FrozenT [24]

Step-by-step explanation:

(cot x \: sinx)(secx - cosx) =  {sin}^{2} x \\  \\ lhs = (cot x \: sinx)(secx - cosx)  \\  =  (cot x \: sinx) \times secx \\- (cot x \: sinx) \times cosx \\  \\  =  \frac{cosx}{sinx}  \times sinx \times secx\\ -  \frac{cosx}{sinx}  \times sinx \times cosx \\  = cosx \times secx - cosx \times cosx \\ =  1 -  {cos}^{2} x \\  =  {sin}^{2} x \\ =  rhs \\ hence \: proved
