Foehn – the hot winds blow along the northern slopes of the 

As `L_(1)andL_(2)` are normals to `x^(2)+y^(2)=72`, they must be of the form y=mx. Sloving it with parabola `4x^(2)-4x-24y+49=0`, we have `4x^(2)-4x-24mx+49=0` `or4x^(2)-4x(1+6m)+49=0` Since the lines touch the parabola, D=0 `or16(6m+1)^(2)-16xx49=0`...
