Best ResponseYou've already chosen the best response.1cosine = adjacent / hypotenuse sine = opposite / hypotenuse tangent = opposite / adjacent

Best ResponseYou've already chosen the best response.1the question states cosine of x equals 1 over 2 so you can determine the length of the adjacent side, and the hypotenuse
