HELP WITH GEOMETRY!! SOH-CAH-TOA
Use the image below to answer the following question. Find the value of sin x° and cos y°. What relationship do the ratios of sin x° and cos y° share?

A right triangle is shown with one leg measuring 4 and another leg measuring 3. The angle across from the leg measuring 3 is marked x degrees and the angle across from the leg measuring 4 is marked y degrees.

Answer 1

try drawing it for more easy understanding

Answer 2

okay

Answer 3

Answer 4

so do you know sin x = ? using sides what side divide what side ?

Answer 5

3/4?

Answer 6

you dont know it right

Answer 7

no

Answer 8

the sin law say sin x = opposite side divide hypothenuse - yes ?

Answer 9

yes

Answer 10

ok using this how can you rewriting than the sin x = ?

Answer 11

sin(x)=cosine(y)?

Answer 12

using what i have wrote above - using these sides - opposite side divide hypothenuse

Answer 13

I do not understand

Answer 14

i remember this

Answer 15

ok - do you know the pythagora s theorem ?

Answer 16

a^2+b^2=c^2

Answer 17

yes so with these knowladge can you calcule the length of hypothenuse of this right triangle ?

Answer 18

3/4

Answer 19

or without calcules do you know what are pythagora s numbers ?

Answer 20

No

Answer 21

@ibrafacts can you help for medal in this question please ?

Answer 22

Do you know that answer?

Answer 23

so than one side has length 3 and the other side has length 4 how many will be the length of hypothenuse ?

using pythagora s theorem - can you calcule it now ?

Answer 24

What is a b and c?

Answer 25

yes using them

Answer 26

is it 3^3+4^2=c^2?

Answer 27

exactly so in this case c= ?

Answer 28

25?

Answer 29

not c^2 so just c= ?

Answer 30

5

Answer 31

yeah sure i can help

Answer 32

yes right

so remember than in case of a right triangle there are one side length is 3 and the other side length is 4 so than the length of hypothenuse will be sure 5

these mean pythagora s numbers - ok. ?

Answer 33

So would I write as the answer:
You would use the Pythagorean theorm and plug in which will give you the answer of 5.

Answer 34

no - the answer is other - first you know now that the length of hypothenuse is 5

so and using this you can rewrite the law of sinus in case of sin x = ?

Answer 35

sin=opp/hyp

Answer 36

just use these above wrote

yes ibrafacts exactly

Answer 37

but please you give possibilitie to collaborate the asker - ok. ?

Answer 38

okay
