ct=a+b221 D, E and F are the mid poiABC. Find the ratio of a

Answer»

X/a + y/b = a+b

⇒y/b = a + b - x/a .................. i

x/a² + y/b² = 2 ................ii

⇒x/a² + y/b x1/b = 2

⇒x/a² + a+b/b- x/ab= 2 puttting i

⇒x(b-a)/a²b = (b-a)/b

⇒x = a²

so x = a²

using ii we get

y = b²

so x=a² and y=b²ANSWER
