Best ResponseYou've already chosen the best response.0errr but we're only given 1 side and 1 angle with 2 unknowns though ?!

Best ResponseYou've already chosen the best response.1@shylibra16 For simplicity, call the sides x, y, and 8. Of the three sides x, y, and 8, which one is the hypotenuse?

Best ResponseYou've already chosen the best response.1Good. That means the y and the 8 are legs. Now look at the given angle. For that given angle, which side, y or 8, is the adjacent leg?

Best ResponseYou've already chosen the best response.1Hint: adjacent means "next to". Opposite means "across from".

Best ResponseYou've already chosen the best response.1For the 60deg angle, the y side is the opposite leg. For the 60deg angle, the 8 side is the adjacent leg.

Best ResponseYou've already chosen the best response.1We know the angle. We know the adjacent leg. We are looking for the opposite leg. Look above at @Nurali 's helpful figure, and see which trig function relates the angle to the opposite and adjacent legs?

Best ResponseYou've already chosen the best response.1The tangent relates the opposite and the adjacent legs. You get \(\tan 60^o = \dfrac{opp}{adj} \) \(\tan 60^o = \dfrac{y}{8} \) \(y = 8 \tan 60^o\) \(y = 13.9\) You are correct.

Best ResponseYou've already chosen the best response.0so if it's \[\tan60 = \frac{8}{y}\] then \[y[\tan60]=8\] \[y=\frac{8}{\tan60}\] like that? @Nurali
