Answer: ±√2

Step-by-step explanation: A fraction is undefined when its denominator is =0 or undefined. so we need to get 2/3x²-6=0 or undefined. so we can also do 3x^2-6=0. Solving yields ±√2!

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

Can someone help help me

White raven [17]

Answer:

15π/2 ft

Step-by-step explanation:

Arc length is given by the formula ...

s = rθ . . . . . r = radius; θ = central angle in radians

A 135° arc has a radian measure of (135)(π/180) = 3π/4. The radius of a circle with a 20 ft diameter is (20 ft/2) = 10 ft. So, the arc length is ...

s = (10 ft)(3π/4) = 30π/4 ft = 15π/2 ft
