Ahhh need help ajsnskdnm​

Step-by-step explanation:

tan55=8.9/x

x=8.9/tan55

x=6.2cm

9514 1404 393

  (a)  6.2 cm

Step-by-step explanation:

You don't need to know much about trig here. You only need to know that the other acute angle in the triangle is less than 55°, so the measure of side x will be less than 8.9. Only one answer choice qualifies:

  x ≈ 6.2

__

If you actually want to do the trig, as opposed to simply rejecting unreasonable choices, then you want to make use of the tangent relation.

  Tan = Opposite/Adjacent

  tan(55°) = 8.9/x

  x = (8.9 cm)/tan(55°) ≈ 6.23 cm

  x ≈ 6.2 cm

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
