Question

At the bank of a river, by measurement,
a = 18 ft. b = 30 ft. c = 24 ft. d = 14 ft.
How long is x? How long is y?
Picture attached below, please help, I'm confused!

Answer 1

b*4/3 =y
d*4/3= x

Why because 24/18= 4/3 so a*4/3=c

Answer 2

thanks so much!

Answer 3

Its the same triangle but you multiply by a similar scalar

Answer 4

so they are the same then?

Answer 5

shoot

Answer 6

if the red angles are the same then yes both shapes are the same

Answer 7

it didn't work, it says it's still wrong /:

Answer 8

b*4/3 =x
d*4/3= y

actually

Answer 9

i mest up switch the x and y

Answer 10

so x should be 40 ft

Answer 11

how do I solve then? sorry I'm really bad at math.

Answer 12

tell me if that's still wrong

Answer 13

divide by 3 and multiply by 4 thats what (4/3) means

Answer 14

okay, so is x 40 and y the same as x?

Answer 15

d * (4/3)= y

Answer 16

so 10.5?

Answer 17

how did you get 10.5?

Answer 18

14/1 cross multiply 4/3...

Answer 19

for y?

Answer 20

my online schooling says 4/3 is wrong for both.

Answer 21

4/3 is bigger than 1 so the answer should be at least higher than 14 for y

Answer 22

its saying it's incorrect...

Answer 23

thats why i got too

Answer 24

I guess I messed up also, I am removing the offending post lol

Answer 25

It appears that this is similar triangles, but I am having trouble identifying the similar sides.

Answer 26

it's alright, thanks for trying.

Answer 27

That is using the 18:24 :: 30:x
x=740/18=41.111
