With the usual notation `np_r=272.` If `r >1,` then `n+r=`

In DeltaABC with usual notations if r=1, r_(1)=7 and R=3, the DeltaABC is

In DeltaABC with usual notations, if r = 1, r_(1) = 7 and R = 3, " then " DeltaABC is

With usual notation in Delta ABC, the numerical value of ((a+b+c)/(r_(1)+r_(2)+r_(3))) ((a)/(r_(1))+(b)/(r_(2))+ (c)/(r_(3))) is

With usual notation in Delta ABC, the numerical value of ((a+b+c)/(r_(1)+r_(2)+r_(3))) ((a)/(r_(1))+(b)/(r _(2))+ (c)/(r_(3))) is

In a triangle ABC with usual notation b cosec B=a , then value of (b + c)/(r+ R) is

With usual notations,in a Delta ABC the value of prod(r_(1)-r) can be simplified as:

In DeltaABC ,with usual notations r_(1),r_(2),r_(3) are in harmonic progression. If area of Delta ABC is 24 and perimeter is 24 then length of its sides are
