Answer 1

Answer 2

SOH CAH TOA

Answer 3

ok what's next ?

Answer 4

What are the ratios of sinx and cosx?

Answer 5

sin - opposite/hypotenuse

cos - adjacent/hypotenuse

tan - opposite/adjacent

Answer 6

12 is the hypotenuse

Answer 7

sqrt 119 is adjacent

Answer 8

Alright so X has the opposite side XZ, and the adjacent side is YZ and your hypotenuse is XY.

You just have to use the ratios, everything is given :d

Answer 9

I'm still confused

Answer 10

Now do the other.

Answer 11

so we don't what's sin right ??

Answer 12

sin is x ?

Answer 13

and cos is x?

Answer 14

Sinx sintheta same thing lol, I was being lazy with the notation :d

Answer 15

keep in mind that, the "adjacent side" is always next to the angle in question, thus is "adjacent to it"

and the "opposite side" is always on the opposite side, or "facing off" the angle in euqestion

Answer 16

^ Beautiful :3

Answer 17

Oh btw with jdoes drawing, and your picture your opposite side is ZY, and adjacent is XZ, so sinX = ZY/XZ.

Answer 18

@Shay17 Do you understand jdoes explanation?

Answer 19

I'm not sure but sinX=sqrt119 and cosX=5 ???
