Two weather tracking stations are on the equator 146 miles apart. A weather balloon is located on a bearing of N 35°E from the western station and on a bearing of N 23°E from the eastern station. How far is the balloon from the western station?
you don't have any choices right?
no
all i have is a diagram attached above
ok
could you help me figure it out
|dw:1403221229845:dw| |dw:1403221401508:dw|
\(\bf tan(55^o)=\cfrac{{\color{brown}{ y}}}{146+{\color{blue}{ x}}}\qquad tan(67^o)=\cfrac{{\color{brown}{ y}}}{{\color{blue}{ x}}} \\ \quad \\\\ \quad \\ \quad \\ tan(55^o)=\cfrac{{\color{brown}{ y}}}{146+{\color{blue}{ x}}}\implies (146+{\color{blue}{ x}})[tan(55^o)] = {\color{brown}{ y}} \\ \quad \\ tan(67^o)=\cfrac{{\color{brown}{ y}}}{{\color{blue}{ x}}}\implies tan(67^o)\cdot {\color{blue}{ x}}={\color{brown}{ y\qquad thus }} \\ \quad \\ {\color{brown}{ y}}={\color{brown}{ y}}\implies (146+{\color{blue}{ x}})[tan(55^o)] =tan(67^o)\cdot {\color{blue}{ x}} \\ \quad \\ 146+x=\cfrac{tan(67^o)}{tan(55^o)}\cdot x\)
im confused i thought i would use laws of sines for this problem where does tan come from
hmmm didn't know you were supposed to use the law of sines...
yea
ohhh shoot then that's simpler =)
i get how to use the laws of sines on this i just dont get how you got 67 and 55
please explain with laws of sines=)
