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
Answer:
1.5
Step-by-step explanation:
The constant of proportionality is the slope
m= (y2-y1)/(x2-x1)
Pick any two points
m = (12-6)/(8-4)
= 6/4
= 3/2
= 1.5
Answer:
y=0.5x+4
Use y2-y1/x2-x1 to find the slope:
3-6/-2-4
Sub in the x and y-values into y=0.5x+b
6=0.5(4)+b
Solve and b=4
Answer: 6 %
Step-by-step explanation: 6 % of 12.5 = 0.75. 12.5 plus 0.75 = 13.25
