28 a toy is made
rings stacked on a base, as shown in the diagram. the
ameter of ring 1 is 87% of the diameter of the base. for ring 2 through ring
her of each ring is 87% of the diameter of the ring directly below it.
base
the diameter of the base is 5 inches. which function can be used to find the diameter in
inches of ring r, where 1 f
d(r) = 5(0.87)

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
