Answer 1

Is thee a pic i can refer too?

Answer 2

I'm trying to get it

Answer 3

Ill help you out when you have the picture

Answer 4

Tag me when you get it?

Answer 5

@CallMeEmmie

Answer 6

I think it's A

Answer 7

what grade are you in

Answer 8

11

Answer 9

I cant help than I am only in 6ths

Answer 10

Hint:
The two smaller triangles are similar triangles. So we can form this proportion
a/6 = 6/8

Answer 11

ok

Answer 12

tell me what you get when you solve for 'a'

Answer 13

I did it different

Answer 14

how did you do it?

Answer 15

I did 18/a = a/8

Answer 16

and I'm still confuse

Answer 17

and I also did like 18/b=b/8 and I got 72

Answer 18

you can't add the 10 and 8 to get 18

Answer 19

oh ok

Answer 20

when you solve `a/6 = 6/8` for 'a', what did you get?

Answer 21

I think you suppose to find the common denominator

Answer 22

so 2in to 6 will be 3 and 2 goes into 8 4

Answer 23

why not multiply both sides by 6 ?

Answer 24

try that and see what you get

Answer 25

8a=36

Answer 26

now divide both sides of `8a = 36` by 8 to isolate 'a'

Answer 27

36/8=4.5

Answer 28

good

Answer 29

a = 4.5 or a = 9/2

Answer 30

now use that value of 'a' and the pythagorean theorem to find 'b'

Answer 31

4.5x4.5=20.5

Answer 32

that's the value of a^2, yes

Answer 33

ok

Answer 34

one of your steps will have

a^2 + 6^2 = b^2

solve for b

Answer 35

6x6=36

Answer 36

yes

Answer 37

ok

Answer 38

a^2 + 6^2 = b^2
turns into
20.25 + 36 = b^2

Answer 39

s0 56.25

Answer 40

that's the value of b^2

but we want the value of b

Answer 41

so find the square root of 56.25

Answer 42

yes

Answer 43

7.5

Answer 44

correct, b = 7.5

Answer 45

or b = 15/2

Answer 46

oh ok

Answer 47

lol ya'll are doing it wrong. im in 12th grade..this pellet is easy. ur gonna get it wrong

Answer 48

since 15/2 = 7.5

Answer 49

how

Answer 50

and ok

Answer 51

I'm still here

Answer 52

so it's B

Answer 53

Summary:
a = 4.5 or a = 9/2
b = 7.5 or b = 15/2

Answer 54

B should be my correct answer
