Geometry please help (pentagons)

Mathematics
1 answer:
SashulF [63]1 year ago
3 0

Answer:

144

Step-by-step explanation:

540 degrees is the sum of angles in a pentagon

Divide 540 by 5(number of sides) =108(interior angle)

Since there are two pentagons you do 108 X 2 = 216 degrees

Do 360 - 216 = 144

so your answer is right

GEOMETRY- FIND POLYGON AREA
Dvinal [7]

Answer:

Step-by-step explanation:

The area of a regular polygon is

A=\frac{1}{2}ap where a is the apothem and p is the perimeter. Perimeter is simple: just count the number of sides the polygon has and multiply it by 3 (the length of one side).

p = 3(9) is 27 inches for the perimeter.

We have what we need now to find the area:

A=\frac{1}{2}(4.1)(27) and

A=\frac{1}{2}( 110.7) so

A = 55.35 square inches

Write the simplest polynomial function with the given roots 2i, square root of 3, and 4
Volgvan

Answer:

  • y = (x - 4)(x + 2i)(x - 2i)(x + √3)(x - √3) Possible answer
  • y = (x - 4)(x^2 + 4)(x^2 - 3)                    Possible answer

Step-by-step explanation:

The simplest answer is that 2i cannot be a lone root. It must have a twin that is - 2i

√3 has the same sort of rule. It cannot be a root all by itself. It also must have a twin, in this case -√3

So the answer must be

(x - 4)(x + 2i)(x - 2i)(x + √3)(x - √3)      <<< Possible answer

but this can be reduced even further.

  • (x + 2i)(x - 2i) = x^2 - x*2i + x*2i - 4i^2
  • (x + 2i)(x - 2i) = x^2 - 4(i)^2
  • (x + 2i)(x - 2i) = x^2  + 4.               Remember i^2 = - 1

By a similar method (x - √3)(x + √3) = x^2 - 3

So the polynomial is reduced to

(x - 4)(x^2 + 4)(x^2 - 3)  <<<< Answer

If this is not among your answers and the  factored form is not either, please tell me what is.
