If two angles are complementary and one of them is 77°, what is the size of the other angle?

13°

Step-by-step explanation:

Complementary angles add to 90 degrees, therefore,

∠1+∠2=90

We know one of the angles is 77 degrees, so we can substitute that in.

77+ ∠2=90

Subtract 77 from both sides to solve for the angle

∠2=13

So, the angle is 13 degrees

125 yards

step-by-step explanation:

i take 75 plus 50.

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.
