Answer: 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

y = -|x + 4|
The coordinates of vertex of that function is (x; 0).
-|x + 4| = 0
|x + 4| = 0 ⇔ x + 4 = 0 |-4
x = -4
Answer: (-4; 0)
