Best ResponseYou've already chosen the best response.0You can just use some formulas because the given is a special triangle.

Best ResponseYou've already chosen the best response.0you need to trig for this. short side is half of long side because it is half of an equilateral triangle then the other side comes from pythagoras.

Best ResponseYou've already chosen the best response.0dude 20/short side=cos60 & 20 / long side=sin60 whats wrong in it??

Best ResponseYou've already chosen the best response.0there's nothing wrong with it, it's just the harder option.

Best ResponseYou've already chosen the best response.0nothing wrong except that the only reason you know the cosine of 60 degrees is because you know the ratios, not the other way around!

Best ResponseYou've already chosen the best response.0in a 306090, a = short side, b = long side, c = hypotenuse c = 2a ; b = \[ a \sqrt{3}\]

Best ResponseYou've already chosen the best response.0\[\text{long} \text{side}=20\text{Cos}\left[\text{ArcSin}\left[\frac{10}{20}\right]\right]=10 \sqrt{3} \]\[20^2=10^2+\left(10 \sqrt{3}\right)^2, 400=100+300, 400= 400 \]
