It is given to us that a+b is 90 it means angle c = 90 because the sum of all angles of triangle is 180 so when we put cot90=0

We have, (x^2+y^2)(a^2+b^2)=(ax+by)^2 Prove that, \dfrac{x}{a}=\dfrac{y}{b}. ∴ (x^2+y^2)(a^2+b^2)=(ax+by)^2 ⇒ x^2(a^2+b^2)+y^2(a^2+b^2)=(ax)^2+(by)^{2} +2(ax)(by) Using algebraic identity, (x+y)^{2}=x^{2}+y^{2}+2xy ⇒ x^2a^2+x^2b^2+y^2a^2+y^2b^2=a^2x^2+b^2y^{2} +2abxy ⇒ x^2b^2+y^2a^2=2abxy ⇒ x^2b^2+y^2a^2-2abxy=0 ⇒ (xb)^2+(ya)^2-2(xb)(ya)=0 Using algebraic identity, (x-y)^{2}=x^{2}+y^{2}-2xy ⇒ (xb-ya)^2=0 ⇒ xb - ya = 0 ⇒ xb = ya ⇒ \dfrac{x}{a}=\dfrac{y}{b}, proved. Hence, \dfrac{x}{a}=\dfrac{y}{b}, proved.
