Shelly states that the triangles below are similar. Which proportion supports her statement?

StartFraction 8 Over 4 EndFraction = StartFraction 15 Over 10 EndFraction

StartFraction 8 Over 10 EndFraction = StartFraction 4 Over 20 EndFraction

StartFraction 6 Over 4 EndFraction = StartFraction 20 Over 10 EndFraction

StartFraction 8 Over 6 EndFraction = StartFraction 20 Over 15 EndFraction

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

so, it becomes,

hence, first option 'a'   is correct.
