sin x° = cos y° = Please Help, and what relationship they have?
anonymous
  • anonymous
first use the Pythagorean theorem to find the hypotenuse of that triangle
anonymous
  • anonymous
Im not sure how to do that?
anonymous
  • anonymous
I forgot how to do that @nono266
anonymous
  • anonymous
Can you please help me do this @nono266
anonymous
  • anonymous
do you see the red little thing on the triangle?
anonymous
  • anonymous
Yes
anonymous
  • anonymous
The box?

no the hypotenuse. the dotted line. okay so the Pythagorean theorem is pretty simple. a2 + b2 = c2 therefore; 15^2 + 8^2 = c^2 225 + 64 = 289 the sq root of 289 = 17 so c (the red dotted line aka hypotenuse) = 17

So what does sin x° = and cos y° = and how are they related Im not understanding
anonymous
  • anonymous
The definition of sin x is side opposite angle x/hypotenuse
anonymous
  • anonymous
So this means what exactly
anonymous
  • anonymous
What is the measure of the side that is opposite the angle whose measure is x degrees?
anonymous
  • anonymous
I dont know @nono266 I just really need to know what sin x° = and cos y° = and what their relationship is I dont understand this stuff at all

The relationship between sin x and cos y is that they are equal.
anonymous
  • anonymous
and what do they equal
anonymous
  • anonymous
I cant give out the answers as much so heres an exact problem on how to solve it sin = opposite/hypotenuse (SOH) cos = adjacent/hypotenuse (CAH) For x, the opposite side is 6 and the hypotenuse is 10: So sin x° is 6/10 = 3/5 For y, the adjacent side is also 6 and the hypotenuse is still 10: So cos y° is also 6/10 = 3/5 Answer: sin x° and cos y° = 3/5

Thank you :)

If you have questions regarding the process, feel free to ask. If not I hope you ace this! Good luck!

@nono266 how do I find the hypotenuse cx
anonymous
  • anonymous
and would opposite be 8?
anonymous
  • anonymous
the hypotenuse is 17 opposite for x; 8 opposite for y ; 15
anonymous
  • anonymous
Thank you so much :D

You better ace this

Lol I'll try my best

YES XD THANK YOU LMAO SO DAMN TRUE

Wait Whats the Adjacent for Y?
anonymous
  • anonymous
adjacent means next to

I got 0.471 to the nearest thousandth for 8/17

but I got 0.882 to the nearest thousandth for 15/17
