Answer 2

BE/AB = 3/4

5/x = 3/4

5*4 = 3x

3x= 20

x = 20/3

x = 6.67

So AB = 6.67

Use this idea to find the lengths of BC and AC

Answer 3

How do I do that though. Would it be BC and DC

Answer 4

BD/BC = 3/4

4/y =3/4

solve for y to find BC

Answer 5

5.333

Answer 6

good, so BC = 5.33

Answer 7

finally

DE/AC = 3/4

4.5/z = 3/4

solve for z, Round to the nearest hundredth

Answer 8

6?

Answer 9

good, AC = 6

Answer 10

Now what do I do?

Answer 11

you just found AB, BC, and AC

so you found all 3 sides of ABC, you're done

Answer 12

AB = 6.67
BC = 5.33
AC = 6

Answer 13

Oh so I dont have to add them all up?

Answer 14

nope, they don't want the perimeter, just the side lengths of ABC

Answer 15

Thank you soooo much for all your help tonight!!!!
