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
Is means equal to.
59 subtracted from m would be m-59
Answer: 351 = m - 59
So the pattern is x,y so the left is x and the right is y. Just graph it
Well the answer is 4 because 13 in the water
9 more than the ones on the log
so the log has 9 turtles less than the turtles in the water
