Expert Answer:

Dear Student

Say the sides of triangle are a,b,c and area of the triamgle=A

A= 1/2  X base X Height = 1/2 X a X alpha   =1/2 X a X beta=1/2 X a X gama

alpha=2A/a    ==>  1/  alpha^2=  a^2/4A^2   Similarly  beta gma delta squares

1/(alpha)^2   +  1/(beeta)^2   +1/(Gamma)^2   =(1/4A^2 )   (a^2+b^2+c^2)
