For the following questions answer them individually
If a, b, c are all non-zero such that $$2^a = 3^b = 6^c$$, then $$c (a + b) =$$
If $$x + 2y = 19$$ and $$2x + y = 17$$, then the value of $$x^{3y - 4x}$$ is
If the angles of a triangle arein the ratio 3:4:5, then theleast angle is
If $$\frac{b}{a - c} = \frac{a + b}{c} = \frac{a}{b}$$ then a : b : c =
