Answer:
Step-by-step explanation:
Sum of interior angle of any polygon =(n-2) × 180°where n represents the number of sides in any polygon.
Or 1260 =(n-2)x180
Dividing both sides by 180:
7=n-2
Adding both sides by 2 we have :
n=9.
Hence a nanogon will have the sum of interior angles as 1260°.
Answer: 30
Step-by-step explanation:
5+5 = 10
10 + 10 = 20
10 + 20 = 30

Answer:
x=3, y= - 2
Step-by-step explanation:
4x + 3y = 6
x-3y= 9
x=9+3y
4.(9+3y)+3y=6
36+12y+3y=6
15y = - 30
y = - 2
=> x= 9+3y
x= 9+ 3.(- 2)
x= 3
Answer:
Line A
Step-by-step explanation:
Line A crosses 5 at y when it hits 1 at x, meaning that constant of proportionality is 5. Trust me ; D.
Where is this system please ?
