\frac{(n-2)\cdot180}{n}=144\\
180n-360=144n\\
36n=360\\
n=10

Here is the formula for find the one inside of the polygon: 
(n-2).180/n (n shows how many sides does polygon have)
so now we can solve the equation==== (n-2).180/n=144
1144n=(n-2).180
144n=180n-360
360=36n
n=10 
so we call it decagon :)

What’s the value of <br> tan (3arc cos 3/4)
Volgvan
<h2>Answer: -1.469</h2>

This trigonometric function can be written as:

tan (3 cos^{-1} (\frac{3}{4}))   (1)

Firstly, we have to solve the inner parenthesis:

cos^{-1} (\frac{3}{4})= 41.409   (2)

Substituting (2) in (1):

tan (3(41.409))=tan(124.228)   (4)

Finally we obtain the value:

tan(124.228)=-1.469

How to find the equation?
bixtya [17]

Answer:

y = 2x + 60

Step-by-step explanation:

Use the equation for a line: y = mx + b

Where

x and y are points on the graph

and m is the slope, and can be found by finding \frac{rise}{run}


so the slope is 10/5 or 2, since the graph goes up by 10 and over by 5.

so plug into the equation, and you get y = 2x + b

Next, pick a point on the graph, and plug in the x and y coordinates,

for example:

(x,y) = (5,70)

so, 70 = 2(5) + b

then solve for b

60 = b

Then rewrite the equation

y = 2x + 60

What is 2pi/ 5radians in degrees
kramer

Answer:

2/5 * pi radians = 72 degrees

Step-by-step explanation:

To convert radians to degrees, we multiply by 180/pi

2 * pi/5 * 180/pi =

The pi/pi cancels leaving

2/5 * 180

360/5

72

2/5 * pi radians = 72 degrees
