Answer 2

@dan815

Answer 3

sin x° =
cos y° =

Please Help, and what relationship they have?

Answer 4

first use the Pythagorean theorem to find the hypotenuse of that triangle

Answer 5

Im not sure how to do that?

Answer 6

I forgot how to do that @nono266

Answer 7

Can you please help me do this @nono266

Answer 8

do you see the red little thing on the triangle?

Answer 9

Yes

Answer 10

The box?

Answer 11

@nono266

Answer 12

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

Answer 13

So what does sin x° = and cos y° = and how are they related Im not understanding

Answer 14

The definition of sin x is side opposite angle x/hypotenuse

Answer 15

So this means what exactly

Answer 16

What is the measure of the side that is opposite the angle whose measure is x degrees?

Answer 17

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

Answer 19

I just need the answer :(

Answer 20

@nono266

Answer 21

The relationship between sin x and cos y is that they are equal.

Answer 22

and what do they equal

Answer 23

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

Answer 24

Thank you :)

Answer 25

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

Answer 26

@nono266 how do I find the hypotenuse cx

Answer 27

and would opposite be 8?

Answer 28

the hypotenuse is 17
opposite for x; 8
opposite for y ; 15

Answer 29

Thank you so much :D

Answer 30

You better ace this

Answer 31

Lol I'll try my best

Answer 32

This is the first concept I actually am learning in Geometry, Idk how I've even been passing the year XD

Answer 33

YES XD THANK YOU LMAO SO DAMN TRUE

Answer 34

Wait Whats the Adjacent for Y?

Answer 35

adjacent means next to

Answer 36

I got 0.471 to the nearest thousandth for 8/17

Answer 37

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