Answer:

Step-by-step explanation:
Cosine is the adjacent side over the hypotenuse (You can remember sin, cos, and tan by using sohcahtoa or sin = opposite/hypotenuse, cos = adjacent/hypotenuse, tan = opposite over adjacent). I think a picture would help, too.
I attached a picture of what I think the triangle would look like.
If the picture is right (we're assuming it is) and going with what we're given (the triangle was addressed as triangle XYZ, meaning that <u>angle Y is in the middle and that's the one we'll use</u>).
Looking at my picture then:
.
Answer:
Step-by-step explanation:
2/3 x - 4 = - 92
add 4 to both sides
2/3 x = - 88
multiply both sides by 3
2 x = - 264
divide both sides by 2
this is ur answer
Good luck
Hope this helps!
Set a y equation or x equation
x-2y=3
x= 2y+3
plug in the x equation to the other equation
4x-8y=12
4 (2y+3)-8y=12
8y + 12 -8y=12
0=0?? I think this means y=0
plug in the y value to the x equation
x= 2 (0) +3
x= 3
