Calcula la suma de los ángulos internos de los siguientes polígonos: a)pentágono - b)heptágono - c)octágono - d)nonágona
Porfavorr, graciasss

 a)pentágono 540° = 108×5  

b)heptágono 900°≈128.57 ×7

- c)octágono 1080° = 135 × 8

- d)nonágona 1260 = 140 × 9

Step-by-step explanation:

360 ÷ number of sides  = x  Subtract  x from 180 =y measure of interior∠

Multiply y × number of sides == sum of interior angles

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
