Question

If ABC DEF and the scale factor from abc to def is 3/4 what is the length of df? (ba=12)(ac=15)

Answer 1

Calculate BC using pythagoras then you multiply the answer by 3/4 or 0.75

Answer 2

lol what is a pythagora

Answer 3

i didnt learn anything about that.

Answer 4

Nope
DF = AC * (3/4)

Answer 5

Since they are the equivalent sides. No pythagoras needed.

Answer 6

Draw the triangles next to each other then you will see.

Answer 7

okay, so what is df?

Answer 8

Just make sure the equivalent sides are in the same place.

Answer 9

What is ac?

Answer 10

so just make df 15

Answer 11

thanks :)!

Answer 12

you forgot the scale of 3/4

Answer 13

howd you draw that.

Answer 14

oh idk what a scale is or how to use that.

Answer 15

DF = AC * (3/4)
Take AC's length then multiply by (3/4)

Answer 16

how would i multiply that?

Answer 17

Take 15 x 3
Take that answer then divide it by 4.

Answer 18

i got 11.25

Answer 19

Yup.

Answer 20

thanks so much, can you help me with anothe problem

Answer 21

Lol. ok

Answer 22

if abc~def what is the length of ef ( im about to try to draw it out)

Answer 23

You get the scale by dividing 2 equivalent sides.

Answer 24

Scale = DF / AC = 10 / 15

Answer 25

Now EF = BC * Scale

Answer 26

You can also use DE / AB = 4 / 6
It will be the same
4 / 6 = 10 / 15

Answer 27

lol im so lost now

Answer 28

What is 10 / 15?

Answer 29

You can even use 10 / 15 as your scale

Answer 30

EF = BC * Scale
So take BC then multiply it by 10.
Then you divide that answer by 15.

Answer 31

BC = 12
What is 12 x 10?

Answer 32

ef=8

Answer 33

There you go

Answer 34

thanks, now another problem lol?

Answer 35

Noooo. Post it as a new question. I've gotta get back to work. :)
