Answer:
The number 9 is greater than 1 and less than 10, while its factors are 1, 3 and 9, therefore it is a counter example to the statement.
Step-by-step explanation:
There are four odd numbers between 1 and 10, they are: 3, 5, 7 and 9. Let's check the factors for each of them.
For 3:

Therefore 3 is not a counter example to the statement, because it behaves as stated.
For 5:

Therefore 5 is not a counter example to the statement, because it behaves as stated.
For 7:

Therefore 7 is not a counter example to the statement, because it behaves as stated.
For 9:

Therefore 9 is a counter example to the statement, since it can be divided by 1, 3 and 9.
Answer:
a) 77.13
b) 179.97
Step-by-step explanation:
3x + 3x + 4x + 5x + 6x + 7x = (6 - 2) × 180
28x = 720
x = 720/28
x ≅ 25.71
3 × 25.71 = 77.13 = smallest angle
7 × 25.71 = 179.97 = largest angle
