answered-by-expert 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)

In order to ensure optimal health (and thus accurate test results), a lab technician needs to the dogs a daily diet containing a minimum of 24 grams (g) of fat, 36 g of carbohydrates, and 4 g of protein. But the dog should be fed no more than five kg of food a day. Rather than to order dog-food that is custom-blended, it is cheaper to order Food X and Food Y, and blend them for an optimal mix. Food X contains 8 g of fat, 12 g of carbohydrates, and 2 g of protein per kg, and costs Rs0.20 per kg. Food Y contains 12 g of fat, 12 g of carbohydrates, and 1 g of protein per kg, at a cost of Rs0.30 per kg. What is the optimal blend?
