A trigonometric question:
On an ABC triangle , the edges are a, b and c.
(bc)/(b+c)=1/(root3)
m(A)=60 degree angle
what is angle of m(B) ?

Best ResponseYou've already chosen the best response.0if its a right triangle, then the m(B) will equal 30 degrees. if its not a right triangle, then a picture would be helpful

Best ResponseYou've already chosen the best response.0then you could do it the hard way by making a system of equations: b  c = 1 b + c = sqrt(3) and finding your b and c....

Best ResponseYou've already chosen the best response.0then use the law of cosines to find "a" and the law of sines to find all your angles

Best ResponseYou've already chosen the best response.0b = 1+c (1+c) +c = sqrt(3) 1 + 2c = sqrt(3) 2c = sqrt(3)1 c = (sqrt(3)1)/2; b = (1 + sqrt(3))/2

Best ResponseYou've already chosen the best response.0I found a=6 then I found , 12/sqrt(3)=(sqrt(3)1)/sin(B) But couldn't go further

Best ResponseYou've already chosen the best response.0if your a=6 is good; then: sinA sinB)  =  a b sinB = b sin(A)/a

Best ResponseYou've already chosen the best response.0the sin inverse funtion will give you one angle for that taio; but you have to be aware that 2 angles are possible with a positive sin.
