What does the interior angles add up to in a dodecagon

1 answer:

8 0

<span>All sides are the same length and all interior angles are the same size. To find the measure of the angles, we know that the sum of all the angles is 1800 degrees (from above)... And there are twelve angles... So, the measure of the interior angle of a regular dodecagon is 150 degrees.</span>

Which point is on the circle whose equation is x^2 + y^2 = 289

goldenfox [79]

Point 4) (8, -15) is on the circle.

Step-by-step explanation:

Step 1:

To determine which point lies on the circle equation, we substitute the different x and y values in the equation and check to see which best satisfies the values in the equation.

The equation of the circle is $x^{2} +y^{2} = 289.$

Step 2:

When $(x,y) = (-12,12). x^{2} +y^{2} = (-12)^{2} + (12)^{2} = 288.$ 288 ≠ 289.

When $(x,y) = (7,-10). x^{2} +y^{2} = (7)^{2} + (-10)^{2} = 149.$ 149 ≠ 289.

When $(x,y) = (-1,-16). x^{2} +y^{2} = (-1)^{2} + (-16)^{2} = 257.$ 257 ≠ 289.

When $(x,y) = (8,-15). x^{2} +y^{2} = (8)^{2} + (-15)^{2} = 289.$

So the fourth set of values is on the circle.

{(-3.7).(-5, -8), (-6, -1). (-9, -1), (0, -3) }

zhenek [66]

Answer:

The domain is the set of all the values of x, so it would be -3, -5, -6, -9, 0. The range would be every set of y, so it would be 7, -8, -1, -3. Finally, this relation is indeed a function.

Domain: -3, -5, -6, -9, 0

Range: 7, -8, -1, -3

Is it a function? Yes
