Best ResponseYou've already chosen the best response.0So my new equation is \[d=\sqrt{30^2+34^22(30)(24)(\cos(43}))\]

Best ResponseYou've already chosen the best response.2yes but that has to make sense to you.... again http://mathworld.wolfram.com/LawofCosines.html

Best ResponseYou've already chosen the best response.0Your graph made better sense than the link, thank you though, therefore my new anser should be, 20.6m

Best ResponseYou've already chosen the best response.2if **you** are happy with it in the attached diagram we can say  from Law of Cosines  that \( \large a^2 = b^2 + c^2  2 b c\ cos A\) dw:1438643019135:dw

Best ResponseYou've already chosen the best response.0ok so is my new anser 20.6m

Best ResponseYou've already chosen the best response.2dw:1438643119009:dw and \(b^2 = a^2 + c^2  2ac \ cos B\)

Best ResponseYou've already chosen the best response.2it is Pythagoreas expanded dw:1438643242132:dw so \(\large c^2 = a^2 + b^2  2ab \ cos C\)

Best ResponseYou've already chosen the best response.2dw:1438643502160:dw look at this, where C = 90 \(c^2 = a^2 + b^2  2ab \ cos C = a^2 + b^2  2ab \ (0)\) \(c^2 = a^2 + b^2\)
