Best ResponseYou've already chosen the best response.3you have multiple ways. one is to recognize that this is isoceles triangle ( the triangle shape with two equal sides)

Best ResponseYou've already chosen the best response.0i saw that to begin with

Best ResponseYou've already chosen the best response.3which makes the right triangle have internal sum of 90+ 42+w= 180.

Best ResponseYou've already chosen the best response.3cos42= (x/2)/102****

Best ResponseYou've already chosen the best response.0\[(102)*\sin 42=\frac{ w }{ 102 }*102\] \[102 \sin 42=w\] w\[\approx 68\]

Best ResponseYou've already chosen the best response.0so how now that i have found w how do i get x?

Best ResponseYou've already chosen the best response.0half of \(x\) is \(\sqrt{102^268^2}\)

highschoolmom2010

Best ResponseYou've already chosen the best response.0can i have a fraction in the numerator

Best ResponseYou've already chosen the best response.0so \(x=2\sqrt{102^268^2}\)

Best ResponseYou've already chosen the best response.0@highschoolmom2010 you can always just use the cosine of 42 degrees you know don't spare functions with your SOH CAH TOA

Best ResponseYou've already chosen the best response.0\(\bf sin(42^o) = \cfrac{\textit{opposite side}}{\textrm{hypotenuse}} \implies \cfrac{w}{102} \implies \color{blue}{sin(42^o) \times 102} = w\\ cos(42^o) = \cfrac{\textit{adjacent side}}{\textrm{hypotenuse}} \implies \cfrac{\textit{half of "x"}}{102} \implies \color{green}{cos(42^o) \times 102} = \textit{half of "x"}\)

Best ResponseYou've already chosen the best response.0\[\cos (42)\rightarrow 65*102\]

Best ResponseYou've already chosen the best response.0well, if "half of x" = 65, yes

highschoolmom2010

Best ResponseYou've already chosen the best response.0ive done confused myself again

jdoe0001

Best ResponseYou've already chosen the best response.0then again, if you already know that x= 65 * 2, you don't have to do the cosine part :)

Best ResponseYou've already chosen the best response.0\[\sqrt{108^2+68^2}=10868=40\] \[\sqrt{40}=2\sqrt{10}\]

Best ResponseYou've already chosen the best response.0but that doesnt look right

jdoe0001

Best ResponseYou've already chosen the best response.0using the cosine, I get ahemm, something else for "x"

highschoolmom2010

Best ResponseYou've already chosen the best response.3now the number should be above 150, which is so much more amazing than just sqrt(40).
