10. Assume that x and y are positive, use Lagrange 7. (a) Find the lengths of the sides of the triangle with multipliers to find the the given vertices (5,0,0), (0,2,0), (0,0-3). Minimum of f (x, y) =3x - y , subject to the constraint: 2x-2y+5=0. (b) Determine whether the triangle is a right triangle, an isosceles triangle, or neither
