Let's assume

length of Ribbon A is A

length of Ribbon B is B

length of Ribbon C is C

we are given

A=B+20% of B

A=1.2B

B=C-20% of C

B=0.80C

now, we can find relation between A and C

A=1.2B

we can plug B

A=1.2*0.80C

A=0.96C

so,

Ribbon A is 4 % shorter than Ribbon C.......Answer

Answer:

Angle BAC corresponds with side length BC

Side length AC will correspond with angle ABC

Step-by-step explanation:

In a triangle, the side length will correspond to the angle opposite it and vice versa.

That is, the side length opposite angle A corresponds to the side of Angle A

Hence, in the triangle given above ;

Angle BAC corresponds with side length BC, because BC is opposite BAC

Side length AC will correspond with angle ABC, because AC is directly opposite angle ABC.
