sounds like the tune of a hawaiian song, but that's all you need http://www.mathwarehouse.com/trigonometry/images/sohcohtoa/sohcahtoaall.png

hmmm well, I see, you're using the 306090 rule

jdoe0001 Group TitleBest ResponseYou've already chosen the best response.0
well, 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

otherwise, your answer will be in terms of "x" and "y"

in 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 \(\bf \sqrt{3} \times \text{smallest side}\)

454590 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

but yes, for the 454590 rule, 2 sides are equal and the longest is \(\bf \sqrt{2}\) of either side
 one year ago

jdoe0001 Group TitleBest ResponseYou've already chosen the best response.0
well, for that you'd need to use the \(\bf \sqrt{3}\) ratio for the longer side

those are the ratio relationships on a triangle with 306090 angles if I were to stand up yours, it'd look like dw:1375645193671:dw

jdoe0001 Group TitleBest ResponseYou've already chosen the best response.0
so, what part confuses? in a 306090 rule, each side have a ratio relationship, as shown above

jdoe0001 Group TitleBest ResponseYou've already chosen the best response.0
so 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
