Best ResponseYou've already chosen the best response.0@LegendarySadist I know you already helped me with one like this, but this one is a bit different. How do I solve when it has all three variables?

Best ResponseYou've already chosen the best response.0i have it set up like: sin(a)/a=10/b=135/45

Best ResponseYou've already chosen the best response.0When we look for side lengths, it's easier to put the side lengths on top. So \[\large \frac{a}{sin(35)}~=~\frac{45}{sin(135)}\]

Best ResponseYou've already chosen the best response.0I thought that's what we were solving for at first, but since we're not we can ignore it.

Best ResponseYou've already chosen the best response.0oooh okay so its just extra information?

Best ResponseYou've already chosen the best response.0Well the m<B allowed us to find m<A so not really. Me putting in "b" was extra info though.

Best ResponseYou've already chosen the best response.0okay. so just solve the equation above?

Best ResponseYou've already chosen the best response.0and like the last one multiply both sides by 35 to get a alone?

Best ResponseYou've already chosen the best response.0Well sin(35), but yes

Best ResponseYou've already chosen the best response.0\[\large a~=~\frac{45 \times sin(35)}{sin(135)}\]

Best ResponseYou've already chosen the best response.0That's closer, but not exactly it

Best ResponseYou've already chosen the best response.0i put: sin 1 (35*sin(1350/45 into my calculator

Best ResponseYou've already chosen the best response.0There's the problem. We're solving for a, not sina. So no need for asin.

Best ResponseYou've already chosen the best response.0that was my answer when i put that into the calculator

Best ResponseYou've already chosen the best response.0okay wait so im confused now when i multiply both sides by sin 35 is that it?
