问题描述：
The line l₁andl₂ intersect at the point C with position vector i+5j+11K.The equation of l₁ and l₂ are r=i+5j+11k+λ（3i+2j-2k)and r=i+5j+11k+μ(8i+11j+6k),where λ and μ are real parameters.
a)Find,in the form ax+by+cz=d,an equation of the plane which contains l₁ and l₂.
The point A has position vector 4i-j+5k and the line through A perpendicular to the plane and meets it at B.Find,
b)the length of AB
c)the perpendicular distance of B from l₁,giving your answers correct to 3 significant figures.
