Find the measure of the interior angles of the following regular polygons: a triangle, a quadrilateral, a pentagon, an octagon,
kvasek [131]

Answer

Triangle  = 60° ; Quadrilateral  = 90° ; Pentagon  = 108° ; Octagon  = 135° ;

Decagon  = 144° ; 30 -gon  = 168° ; 50 -gon  = 172.8° ; 100 -gon =176.4°

Step-by-step explanation:

You follow the equation (N-2)*180, then divide the answer with the the number of sides. Example for Triangle: (N-2)*180=(3-2)*180=(1)*180=180 then divide by 3 because in a triangle there are 3 sides. 180/3=60.

WHOEVER GETS RIGHT GETS BRAINLIEST!!

Answer:

Answer B:  min. value at -6

Step-by-step explanation:

Complete the square of f(x) = x^2 - 2x - 5.

Note:  Please use " ^ " to denote exponentiation, as shown.

Start with f(x) = x^2 - 2x - 5.

Identify the coefficient of the x term:  it is 2.

Take half of that and square your result:  (1/2)(2) = 1, and then 1^2 = 1.

Add and subtract this 1 between the 2x term and the constant term:

f(x) = x^2 - 2x    + 1   - 1  - 5

Rewrite x^2 - 2x + 1 as a perfect square:

f(x) = (x - 1)^2 - 1 - 5, or    f(x) = (x - 1)^2 - 6

Compare this to the standard form

                                        f(x) = (x - h)^2 + k

We see that h = 1 and k = -6.

The vertex is located at (h, k); here, it's located at (1, -6).

Thus, the minimum value of this function is at the vertex (1, -6).

This agrees with Answer B:  min. value at -6.
