Find the measure of each interior angle of the regular polygon​

Mathematics
1 answer:
lukranit [14]3 years ago
5 0

Answer:

140 deg

Step-by-step explanation:

The sum of the measures of the interior angles of an n-gon is

(n - 2)180

In a 9-gon, there are 9 sides, so n = 9.

The sum of the measures of the interior angles of a 9-gon is

(n - 2)180 =

= (9 - 2)(180)

= 7(180)

= 1260

A regular polygon has congruent interior angles. A 9-gon has 9 congruent interior angles. The measure of each interior angle is the sum of the measures of the interior angles divided by the number of angles.

1260/9 = 140

Step-by-step explanation:

a=3x^2+5x-6\\b=-2x^2-6x+7

atroni [7]

Responder:

$ 16,2

Explicação passo a passo:

No dia da festa, Bianca comprou os pastéis por US $ 5,20, duas maçãs do amor por US $ 3,40 e dois refrigerantes por US $ 7,60. Quanto bianca você gastou?

O valor gasto por Bianca é a soma de todos os itens que ela comprou:

Pastelaria = $ 5,20

Maçãs do amor = $ 3,40

Refrigerantes = $ 7,60

A soma da soma dá o valor gasto de Bianca:

Doces + Maçãs do Amor + Refrigerante

$ (5,20 + 3,40 + 7,60)

= $ 16,2
