If we join the Center with different corners of the polygon,we find 10 Isoceles triangle with equal side=9.14cm, Making an angle of 36° between the equal sides.

Area of 1 triangle= a*b*sinC/2
= 9.14*9.14*Sin36°/2
= 9.14*9.14*0.587/2
=24.51 cm^2

Area of 10 triangle= 24.51*10
= 245.1cm^2

Set R(x) equal to C(x).  Solve the resulting equation for x, paying attention to the domain of C(x):

Solve 200x-2x^2 = -x^2 + 25x + 31000 for x greater than or equal to zero but less than or equal to x.  That means you must reject any solution outside of this domain.

Rearrange all of these terms on the left side of your equation and place zero on the right side.  Next, rearrange all of the terms on the left side in descending order by powers of x.  Next, solve the resulting quadratic equation.  Make certain to reject any x that does not fall within [0,100].

Solve for x and find the value of the unknown angle measures.
snow_tiger [21]

Answer:

x = 20

m = 92

n = 68

p = 92

Step-by-step explanation:

x = 20

2 + 3x = 62

-2           -2

----------------

   3x = 60

  -----   -----

    3       2

    x = 20

m = 92

20 + 68 = 88

180 - 88 = 92

n = 68

The vertical angle is 68 degrees

p = 92

Vertical angle is m, which is 92.

Hope this helped.
