In a triangle ABC,(r_(1)-r)/(a)+(r_(2)-r)/(b)+(r_(3)-r)/(c)=

In triangle ABC, 2b=a+c .If r_(1),r_(2),r_(3) be the exradii of the triangle,then (1)/(r_(1)),(1)/(r_(2)) and (1)/(r_(3)) are in

In triangle ABC ,if (r_(1))/(6)=(r_(2))/(3)=(r_(3))/(2) ,where, r_(1),r_(2) and r_(3) are ex-radii, then find the value of (a)/(b)+(b)/(c)+(c)/(a) ?

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

Prove that in Delta ABC S (( r_1- r_2) /( a) + ( r_2- r)/( b) + ( r_3- r)/( c ) ) = r_1+ r_2+ r_3 Prove that in Delta ABC

In an acute angle triange ABC, a semicircle with radius r_(a) is constructed with its base on BC and tangent to the other two sides r_(b) and r_(c) are defined similarly. If r is the radius of the incircle of triangle ABC then prove that (2)/(r) = (1)/(r_(a)) + (1)/(r_(b)) + (1)/(r_(c))
