Best ResponseYou've already chosen the best response.0the interior angles are b=30, and a=60

Best ResponseYou've already chosen the best response.1right, so you can also use the fact that, side opposite to 60 degree angle is \(\sqrt 3 /2\) times the hypotenuse

Best ResponseYou've already chosen the best response.0For the length of a I tried setting up sin60=a/10

Best ResponseYou've already chosen the best response.1ok, good going, so a = 10 sin 60 and sin 60 is actually \(\sqrt 3 /2\)

Best ResponseYou've already chosen the best response.0so i'm a little confused what i'm supposed to do with the Sqrt(3)/2

Best ResponseYou've already chosen the best response.1multiply it with 10 \(10 \dfrac{\sqrt 3}{2} = 5 \sqrt 3 \)

Best ResponseYou've already chosen the best response.0oh I see, so instead of using the 60 degrees we are just multiplying sqrt(3)/2 by 10
