Answer 1

Two boats start their journey from the same point A and travel along directions AC and AD, as shown below

What is the distance, CD, between the boats?

284.3 ft
115.5 ft
230.9 ft
>173.2 ft

Answer 2

tan (30) = BD /100
tan (60) = BC/ 100

Answer 3

BD-BC= CD

Answer 4

100 SQT 3 = 173.205

Answer 5

attention please !!!

tan 30 = 100/BD
and the second is invers too

Answer 6

the tan law say opposite divide adjacent

Answer 7

@TheSmartOne please

Answer 8

ok. ? correct it please

Answer 9

(100 sqrt 3) -(100/sqrt3) = 116.2

Answer 10

i think this would be correct

Answer 11

i mean 115.47

Answer 12

@agent0smith

Answer 13

tan30=100/BD
tan60 = 100/BC

BD = 100/tan30
BC = 100/tan60

CD = BD -BC = 100/tan30 - 100/tan60

do you can solve it this now please ?

Answer 14

tan30 = (sqrt3)/3
tan60 = sqrt3

Answer 15

thats what i did . tan 30 = \[\sqrt{3/(3)} = \sqrt{3}\]

tan 60 = \[\sqrt{3}\]

Answer 16

so then \[100 \sqrt{3}\] \[100/ \sqrt{3}\]

Answer 17

173.205- 57.735 = 115.47

Answer 18

300/sqrt3 -100/sqrt3 = 200/sqrt3 = 200*sqrt3 /3 = 200*1,73 /3 = 346/3 = 115,3

so CD = 115,3

approximately like my result so i think is right now

ok. ?

Answer 19

Smith do you agree this ?

Answer 20

please

Answer 21

ty

Answer 22

i don't really understand what you did but we got the same answer. although mines was a bit more accurate

Answer 23

100/(sqrt3 /3) = 300/sqrt3
yes ?

Answer 24

were did you get the 300 from?

Answer 25

100/sqrt3 /3 = (100*3)/sqrt3

yes ?

Answer 26

a/(b/c) = ac/b

Answer 27

ok

Answer 28

do you understand it now ? just i ve wrote there directly

Answer 29

nope , i only get it the way i did it. however i'm going to go with 115.47. i think this is right.

Answer 30

thank you for the help . it was correct

Answer 31

np

was my pleasure

good luck

bye bye
