Best ResponseYou've already chosen the best response.1dw:1436927827901:dw well hmmm we know all sides are equal

Best ResponseYou've already chosen the best response.1so once we find a we can say the perimeter is a+a+a or 3a

Best ResponseYou've already chosen the best response.0Ok...... But Idk how to find A. Is there a formula?

Best ResponseYou've already chosen the best response.1I wonder if that is suppose to represent a "radi" of the equilateral

Best ResponseYou've already chosen the best response.1do you think that 6 is suppose to represent the radius of the regular polyngon?

Best ResponseYou've already chosen the best response.0In the original picture the number 6 is more then half or the triangle

Best ResponseYou've already chosen the best response.1I think 6 is the length of the radius of the regular trigon here since the other line segment there is the apothem and I know it is the apothem because it runs perpendicular to a side of the regular trigon

Best ResponseYou've already chosen the best response.1\[radius \dot 2 \sin(\frac{180}{n})=s\]

Best ResponseYou've already chosen the best response.1n represents number of sides

Best ResponseYou've already chosen the best response.1yes 180 divided by 3 is 60 so you have radius*2sin(60)=s

Best ResponseYou've already chosen the best response.0Now what do I do? Multiply the radius by itself or by 2 or what?

Best ResponseYou've already chosen the best response.1multiply the radius the 2 and the sin(60)

Best ResponseYou've already chosen the best response.1dw:1436929098581:dw this is how I got the formula by the way \[\sin(60)=\frac{\frac{a}{2}}{6} \\ \sin(60)=\frac{a}{6 (2)} \\ 6(2) \sin(60)=a\]

Best ResponseYou've already chosen the best response.1you just have to find the product of 6 and 2 and sin(60) you can use a calculator if you want

Best ResponseYou've already chosen the best response.0So I have to find the sin of 60

Best ResponseYou've already chosen the best response.1yes you have to compute 6 times 2 times sin(60)

Best ResponseYou've already chosen the best response.16*times 2 is 12 so 12*sin(60) gives you what ?

Best ResponseYou've already chosen the best response.1are you having trouble doing this ?

Best ResponseYou've already chosen the best response.1you could put sin(60) in a calculator or if you learned any unit circle stuff you can find sin(60) exactly on the unit circle

Best ResponseYou've already chosen the best response.1there is also another way I can derive it for you dw:1436929558610:dw use Pythagorean theorem to find the height

Best ResponseYou've already chosen the best response.1\[2^2=h^2+1^2 \\ 4=h^2+1 \\ 3=h^2 \\ \sqrt{3}=h\]

Best ResponseYou've already chosen the best response.1\[\sin(60)=\frac{opp}{hyp}=\frac{\sqrt{3}}{2}\]

freckles

Best ResponseYou've already chosen the best response.1I don't know I would have to find a calculator and do 12*sqrt(3)/2 aka 6*sqrt(3) \[6\sqrt{1} < 6 \sqrt{3} <6 \sqrt{4} \\ 6<6 \sqrt{3}<6(2) \\ 6 <6 \sqrt{3}<12\] so it seems like you are in the ball park the number is between 6 and 12 and probably a bit closer to 12 than 6 ...but let me get a calculator to approximate 6sqrt(3)

freckles

Best ResponseYou've already chosen the best response.1yes 6 sqrt(3) is 10.39 approximately
