Question

help!?!?
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?

Answer 1

\[\sqrt{3^3+4^4}=hypotenuse = 5\]

Answer 2

cos=adj/hyp
sin=opp/hyp

the opposite side of angle x is 3 and the adjacent side of angle y is also 3, (the hypotenuse is the same for both )

Answer 3

So cos y= sin x

Answer 4

See how I did it?

Answer 5

yes thanks for the help !

Answer 6

YW!

Answer 7

You can also just remember that this is a 3-4-5 triangle.

Answer 8

Just like 6-8-10 , 12-16-20
and so on.
