    if a/c=1/ 2 then c=2a or a=c/2 ; then in formula above, you express a as c/2 whatever the ratio is, use it to express side a in terms...

    in this case yes [ATTACH] in your drawing the angle would be between c and b since given the ratio between the other two sides, use...

    Shouldnt it be the angle between a and b instead of alpha in the expression?
