120 dived by 3 multiplied by 2 is equal to 80 packs of crisps
knowed that the 3rd side of a triangle need being greater than the difference of the given two sides length and less that the sum of the given two sides length
so with these knowledge we get
x > (9-6) so x > 3
and
x < (9+6) so x < 15
from these result that the 3rd side length can being choice B. 4 ,C. 7,F. 10,
E. 12,
hope this will help you .

For 1st fig:
Angles whose measure is greater than angle 8 is:
<4,<5,<9
For 2nd fig:
Angles whose measure is less than angle 4 is:
<2,<5,<7
▶Explanation:
❇Statement of Exterior angle inequality theorem:
↪An exterior angle of a triangle is greater than either of the non-adjacent interior angles.
➡So for 1st fig ,< 4,<5,<9 were exterior angles of triangle which would obviously be greater angle than interior angle 8 by the theorem.
➡Similarly, for 2nd fig, <2,<5,<7 were non adjacent interior angles which would obviously be less in measure than exterior angle 4.In this case , see both triangles to not get confused.
