How many sides does a regular polygon have if one exterior angle is 1 degree

Mariulka [41]

Answer:

The number of sides are 360

Step-by-step explanation:

We are given

exterior angle is 1 degree

Firstly, we will find interior angle

interior angle = 180 - exterior angle

we can plug value

interior angle = 180 - 1

interior angle = 179

now, we can use formula

$\frac{180(n-2)}{n}=\theta$

now, we can plug angle

$\frac{180(n-2)}{n}=179$

now, we can solve for n

$180\left(n-2\right)=179n$

$180n=179n+360$

$n=360$

So,

The number of sides are 360

Does anyone know how to do number 1

Tpy6a [65]

I believe it's saying whatever you measure the angle for in 4 is the same as 5. You could probably figure it out by knowing it's an acute and that the two together make a square. (Angles altogether equal 360, 180 a side)

The table shows some of the values of a function of the form y=ax^2+bx+c which is the value of c, the constant, the constant for

cupoosta [38]

Answer:

$c=8$

Step-by-step explanation:

Given: $y=ax^2+bx+c$

To find: c

Solution:

At $x=4,y=48$ :

$48=16a+4b+c$ (i)

At $x=5,y=73$ :

$73=25a+5b+c$ (ii)

At $x=6,y=104$ :

$104=36a+6b+c$ (iii)

On subtracting (i) and (ii),

$25=9a+b$ (iv)

On subtracting (i) and (iii),

$56=20a+2b\\\\28=10a+b \,\,\,\,(v)$

On subtracting (iv) and (v),

$a=3$

Put a=3 in (iv)

$25=9(3)+b\\25=27+b\\25-27=b\\-2=b$

Put $a=3,b=-2$ in (iii)

$104=36(3)+6(-2)+c\\104=108-12+c\\104=96+c\\104-96=c\\8=c$

HELP PLEASE ASAP!!! Khan Academy unit test!

Answer:

As=0.13

Step-by-step explanation:

If we have central angle we use this rule to find area of sector :

$As=\pi r^{2}(\frac{C}{360})$

C is central angle. r is radius.

$As=\pi *9*\frac{\frac{9\pi }{17} }{360} =\\\\As=\pi *9*\frac{9\pi }{17*360} =\\\\$

Evaluate :

$\frac{798.63}{6120}=0.13$
