Best ResponseYou've already chosen the best response.0hmmm well, I see, you're using the 306090 rule

Best ResponseYou've already chosen the best response.0well, hmm, still the 306090 rule wouldn't end up using the sine function anyhow I mean you're given an angle's value, 30 degrees so I gather you're expected to use sine and cosine for that

Best ResponseYou've already chosen the best response.0otherwise, your answer will be in terms of "x" and "y"

Best ResponseYou've already chosen the best response.0in a 306090 rule the smallest side, will half the longest that is "x" the smallest, is half 40 the longest and the OTHER side, is \(\bf \sqrt{3} \times \text{smallest side}\)

Best ResponseYou've already chosen the best response.0454590 assumes you have 2 angles of 45 degrees you have there one of 30, and is a right triangle, so you have another of 90 and lastly one of 60

Best ResponseYou've already chosen the best response.0but yes, for the 454590 rule, 2 sides are equal and the longest is \(\bf \sqrt{2}\) of either side

jdoe0001

Best ResponseYou've already chosen the best response.0well, for that you'd need to use the \(\bf \sqrt{3}\) ratio for the longer side

Best ResponseYou've already chosen the best response.0those are the ratio relationships on a triangle with 306090 angles if I were to stand up yours, it'd look like dw:1375645193671:dw

Best ResponseYou've already chosen the best response.0so, what part confuses? in a 306090 rule, each side have a ratio relationship, as shown above

jdoe0001

Best ResponseYou've already chosen the best response.0so you want to know what "x" is in the triangle notice that the triangle has a hypotenuse of 40 and 2 angles, a 30 degrees one and a 90 degrees one the other internal angle has to be a 60 degrees one so that makes it a 306090 triangle, whose side relationships are well known
