What is the value of x?<br><br><br><br> Enter your answer in the box.<br><br> x =
sp2606 [1]

we are given three angles

first angle =x-4

second angle =3x

third angle =100

we can see that this is a triangle

and we know that

sum of all angles in any triangle is always 180

so,

first angle + second angle + third angle =180

now, we can plug values

and we get

x-4+3x+100=180

now, we can solve for x

4x+96=180

4x+96-96=180-96

4x=84

x=21................Answer

An escalator in a department store makes an angle of 45∘with the ground. How long is the escalator if it carries people a vertic
andreyandreev [35.5K]

Answer:

Length of the escalator is 33.94 feet.

Step-by-step explanation:

In the attached figure we can see that

sin(\theta )=\frac{V}{L}

It is given that

angle = 45

Vertical Height 'V' = 24 feet

Applying values in the above equation we get

sin(45^{o})=\frac{24}{L}\\\\\frac{1}{\sqrt{2}}=\frac{24}{L}\\\\ \therefore L=24\times \sqrt{2}\\\\L=33.94feet

goldenfox [79]
Leave the sequence organized

4 , 6 , 8 , 9, 10, 10, 12, 37, 40, 365

We have 10 number

Median = (n+1)/2

Mp = (10 + 1)/2

Mp = 5,5

We have to calculate the median between the term 6 and 5

Median = (term6 + term5)/2

Median = (10+10)/2

Median = 10
