Question 393628: God bless you and hope you will clear my frustration to this nagging and seemingly wrong formula. We have a triangle with sides a, b and c with c as base, which is divided into two parts in r to s ratio, by altitude denoted by h. I.e. side a is hypoteneuse to r and side b to s. Is there a formula which runs as, h = [a * s + b * r] / r + s. Many engineers vehemently declared the wrongness of the formula
