alrighty
so we solve for the angle that is
huh, the thing below shows that it's 25 degrees, that's helpful
anyway
see my diagram
ok, we are saying that angle c=25 degrees
that makes angle b 90-25 or 65 degrees
so [tex]\theta[/tex] will be angle c
herm
the the ratios
ok, sin=oposite side/hytpohuse
cos=adjscent/hypotonuse
tan=oposite/adjacent
sin(c)=y/3
cos(c)=x/3
we can multiply both sides by 3 to get
3sin(c)=y
3cos(c)=x
use your calculator and c=25 degrees (set your calculator to degrees or use 5pi/36 radians)
3sin(25°)≈1.26785=y
3cos(25°)≈2.71892=x
rounded to nearest tenth
