How many sides does a regular polygon have with one central of 18 degrees?

Natalka [10]

All of the centra angles in a regular polygon must add up to 360 degrees. Also, because you're told that it is a regular polygon, the "regular" indicates that all of the central angles will be the same. Divide 360 degrees by 18 degrees to get the number of central angles, which is the same as the number of sides. 360/18 = 20. Therefore, the polygon has 20 sides. Hope that helps!

Graph the equation by plotting three points. If all three are correct the line will appear -3y=-2x-6

Pachacha [2.7K]

Three possible points are:
(-3, 0)
(0, 2)
(3, 4)

To find any points, simply select any value for x. Input that value, then find the corresponding y-value.

For example, if x = 0, then:

-3y = -2(0) - 6
-3y = -6
y = 2

PLEASE HELP ME The length of the one of the legs of a right triangle is 8m and the hypotenuse is 12m. Which of the following cho

Bas_tet [7]

Answer:

The length of the other leg is 8.94 m.

Step-by-step explanation:

Given that,

Hypotenuse of a right triangle is 12 m

The length of the one of the legs of a right triangle is 8 m

We need to find the length of the other leg. It is based on the concept of Pythagoras theorem. Let the other leg is h. So, according to this theorem,

$H^2=b^2+h^2$

H = hypotenuse = 12 m

b = base = 8 m

$h^2=H^2-b^2\\\\h^2=12^2-8^2\\\\h=\sqrt{80}\\\\h=8.94\ m$

So, the length of the other leg is 8.94 m.
