Question

LIL HELP PLZZ MEDAL & FAN!!!

Answer 1

okay i know the answer... But not sure how to explain really... lol

Answer 2

12 goes into 72 by how much?

Answer 3

11 goes into 66 by how much?

Answer 4

so what does 12x?=72

Answer 5

what does 11X?=66

Answer 6

A scale factor is the ratio of two similar geometric figures. To find this, you divide the number of one side of the larger shape by the same side on the smaller shape (eg, sides BC and EF on the similar triangles shown).

With this you get 66/11. It is important that you simplify the fraction as much as you can to get your answer, and check with the same method on the other corresponding sides.

Answer 7

and which one is the answer?

Answer 8

If you don't get it, let's try the same thing for sides AB and DE.
\[AB \div DE = \frac{ 72 }{ 12 }\]
Again, it is important that you simplify this fraction to get the answer, and check with the other sides.

Answer 9

@Directrix

Answer 10

Tri ABC~ Tri DEF which means that corresponding sides are in proportion. The ratio of any two corresponding sides gives the scale factor.

Answer 11

From this statement of how the vertices match, Tri ABC~ Tri DEF, we know that

the ratio of side AB to side DE will give the scale factor.

So, look at the diagram and get the measure of side AB and also side DE. Post what you get.

Answer 12

@Adam96

Answer 13

C?

Answer 14

I did not ask the answer. I'm asking you to look at the diagram.

Answer 15

So, look at the diagram and get the measure of side AB and also side DE. Post what you get.

Answer 16

i already did!

Answer 17

I don't see it.

measure of side AB =

side DE =

Answer 18

so its D!

Answer 19

Look at the diagram for this problem and read off these measures:

measure of side AB =

side DE =

Post what you get, okay? @Adam96

Answer 20

i got D

Answer 21

Look at the diagram for this problem and read off these measures:

measure of side AB =?

side DE = ? Post what you get, okay? @Adam96
