Best ResponseYou've already chosen the best response.4This is very similar to the kind of problem I taught you before.

Best ResponseYou've already chosen the best response.1Well I looked at the triangle and saw that like EF is opposite and DE is adjacent sooo I use tan?

Best ResponseYou've already chosen the best response.4Very good. Keep going. Use tangent to set up the equation.

Best ResponseYou've already chosen the best response.1:3> xD thanks Okay, um Tan(45) = x/55 ?

Best ResponseYou've already chosen the best response.4Looks good. Solve for x and then round to the nearest hundredth like they ask.

Best ResponseYou've already chosen the best response.4Oh wait. One problem with your equation. The angle isn't 45.

Best ResponseYou've already chosen the best response.1lol derp. 49 Tan(49) = x/55 x= 2,695

Best ResponseYou've already chosen the best response.4I don't know what you did, but 2,695 is super super off.

Best ResponseYou've already chosen the best response.1D: I thought it was 49 x 55 to find out x to then divide it and then make it like...right =2695/55 = 49

Best ResponseYou've already chosen the best response.4TANGENT of 49... super different from 49. Use your calculator to find out what tan(49) is. Make sure you're in degrees and not radians.

Best ResponseYou've already chosen the best response.4tan(49) = x/55 Just solve for x, then let your calculator do the trig function for you.

Best ResponseYou've already chosen the best response.4It really doesn't have sin cos tan buttons on it? You'll need to use a different calculator then, or else use google or alpha.

Best ResponseYou've already chosen the best response.1ohhh like tan(49) = 1.15/55 ?

Best ResponseYou've already chosen the best response.4Far left, below pi, you'll see the buttons sin, cos, and tan. Those are your trig functions. To do this one, click tan, then 49, then ). Should look like this: I've boxed the trig function buttons in blue and the way to switch between degrees and radian modes in green.

Best ResponseYou've already chosen the best response.4Becca, please don't forget how to do simple algebra. tan(49) = x/55 How do you solve for x?

Best ResponseYou've already chosen the best response.4Yes. Let me just show you the last 2 steps. You got as far as tan(49) = x/55 multiply both sides by 55. That's basic algebra, solving for x. 55*tan(49) = x tan of 49, when you put in your calculator is 1.15036841 and 55*(1.15036841) = 63.2702625 then, of course you round to the nearest hundredth.
