Best ResponseYou've already chosen the best response.0sohcahtoa cos so we use ah a is the adjacent side length, h is the hypotenuse so lets draw our triangle dw:1434628807787:dw

Best ResponseYou've already chosen the best response.0the opposite side length is opposite the angle and adjacent is the one left over

Best ResponseYou've already chosen the best response.0if it is asking cosB then cosB=a/h lets label our triangle dw:1434629018296:dw cosB=adjacent/hypotenuse you can finish it

Best ResponseYou've already chosen the best response.0@amorfide It must be cos B (and that is the usual way of labelling triangles) @HWBUSTER00 This is about geometry and is using 'general' notation. You do not need actual numbers (e.g. lengths or angles) to answer the question in 'letters' The cosB is the adjacent side divided by hypotenuse each of those sides is denoted by a letter a,b or c so the answer (as seen ) is a fraction made of letters (such as x/y) you do not need numbers to answer 'general' equations

Best ResponseYou've already chosen the best response.0WHICH MEANS THAT THE CAPITAL A,B,C are the angles

Best ResponseYou've already chosen the best response.0while the a,b,c are the sides

Best ResponseYou've already chosen the best response.0it is 'adjacent divided by hypotenuse' but you have written hypotenuse divided by adjacent just try again  you have the correct sides  in the wrong order

Best ResponseYou've already chosen the best response.0OK good now can I ask you to stop a moment an ask WHY you hate these trig functions? They are simply divisions (or ratios) of the sides and there are only 3 to remember right now.

Best ResponseYou've already chosen the best response.0they are to complicated ????? I dont know maybee it is because my ocd ???? i hate it when numbers are not there ..........it is so frustrating

Best ResponseYou've already chosen the best response.0dw:1434629727102:dw in these triangles the angle is always the same If oyu divide the opposite by the adjacent you ALWAYS get the same

MrNood

Best ResponseYou've already chosen the best response.0In th above case this answer is the TAN of the angle but the SAME appies to the the ratio between other sides. If oyu have studied similar triangles you can see why th eratio is always the same

Best ResponseYou've already chosen the best response.0do you know how to do this on http://static.k12.com/eli/bb/817/1/0/2_36843_44974/1/d064582a0cf3fa6c8783e88a968d415900f4a14e/media/cf27c592a79e2dbe6cffe23d1941dce276408f01/mediaasset_652591_1.png

Best ResponseYou've already chosen the best response.0The actual number is not important  you can see if you keep the angle th esame, but increae the length of a side then the OTHER sides increase by the same scale factor. THEREFORE the ratio of the sides stays the same provided trh eangle is the same  and those ratios are sine, cosine, and tangent

Best ResponseYou've already chosen the best response.0I DO know how to do the second one  but it is more important that YOU do If you look at the angle Z (49 deg) then what is the 'name' of the side z (opposite, adjacent or hypotenuse) What is the 'name' of the side labelled 4?

MrNood

Best ResponseYou've already chosen the best response.0OK  you need to look at the way th etriangles are labelled  once oyu see this then the functions are easier Look at angle Z Look at side z in relation to Angle Z where is side z (opposite, adjacent or hypotenuse) hint  the hypotenuse is ALWAYS the longest side and is ALWAYS opposite the right angle (90 deg)

MrNood

Best ResponseYou've already chosen the best response.0ok good and now th eside labelled 4? is that opposite, adjacent or hypotenuse

MrNood

Best ResponseYou've already chosen the best response.0in relation to Angle Z where is side labelled 4 (opposite, adjacent or hypotenuse)

MrNood

Best ResponseYou've already chosen the best response.0OK so for angle Z we know Angle Z= 39 deg Opposite side = z Adjacent side = 4 Which of the functions (sin cos and tan) uses Opposite and adjacent?

MrNood

Best ResponseYou've already chosen the best response.0you must have seen these  there are 3 to remember and there are many ways on the web given to remember them sine = O/H cosine = A/H Tangent = O/A so which one uses Opposite side and Adjacent side?

Best ResponseYou've already chosen the best response.0I have no idea what those numbers are I you want ot understand these functions please answer the above: sine = O/H cosine = A/H Tangent = O/A so which one uses Opposite side and Adjacent side? THEN for angle Z we know Angle Z= 39 deg Opposite side = z Adjacent side = 4

Best ResponseYou've already chosen the best response.0I don't really care about the answer  I can do it in my head I want you to go away not 'hating' trig functions Do not worry about the numeric answer  concentrate on the method I am showing you. Please tell me if you are not interested in any of this....and only want the answer

Best ResponseYou've already chosen the best response.0so one side of the triangle always less than the other

MrNood

Best ResponseYou've already chosen the best response.0OK  I'm out of here  I have tried to show oyu the method but you do not seem to want ot follow it. sine = O/H cosine = A/H Tangent = O/A so which one uses Opposite side and Adjacent side?

Best ResponseYou've already chosen the best response.0my intention was not for you to do my work . it was to help with the question but you decided to give me a whole math lesson for witch I already told you i dont understand. you are being pretty rude and i dont appreciate it. and for some reason you want to take control and i dont know why . it was question .

Best ResponseYou've already chosen the best response.0This a maths forum  I am here to give maths 'help' call it a lesson if oyu want. I have asked oyu to do a few simple steps which would guide you to the answer and I have tried to expand the concept so that see what oyu are doing is not inherently difficult. I asked several times for you to answer THIS (below) because it is the next KEY steo to getting the answer you want, but oyu have answered something else, or answered without giving any thought to what I asked. You have left the forum in th emiddle of help without notice. So I feel it is YOU who is not being polite. IF you can refer back to what has been discussed and explained in the above posts then you can answer the following: sine = O/H cosine = A/H Tangent = O/A so which one uses Opposite side and Adjacent side?
