बिन्दु `(1,2-4)` से होकर जाने वाली उस रेखा का समीकरण ज्ञात कीजिए जो रेखाओं
`(x-8)/(3)=(y+19)/(-16)=(z-10)/(7)` और `(x-15)/(3)=(y-9)/(8)=(z-5)/(-5)` पर लम्बवत है।

Consider the lines (x-5)/(3)=(y-7)/(-16)=(z-3)/(7) and (x-9)/(3)=(y-13)/(8)=(z-15)/(-5) , then-

Find the shortest distance between the lines given by (x-8)/(3)=(y+9)/(-1)=(z-10)/(7)and(x-1)/(3)=(y-2)/(8)=(z-5)/(-5)

(x)/(4)=(y)/(3)=(z)/(2),7x+8y+5z=62

Show that the lines (x-3)/(2)=(y-5)/(-1)=(z+7)/(4) and (x-15)/(4)=(y+12)/(-2)=(z-8)/(8) are parallel.

Find the shortest distance between the lines. (x-8)/3.(y+9)/-16 = (z-10)/7 and (x-15)/3 = (y-29)/8 = (z-5)/-5 .

Find the vector equation of the line passing through the point (1, 2, -4) and perpendicular to the two lines : (x-8)/(3)=(y+19)/(-16)=(z-10)/(7) and (x-15)/(3)=(y-29)/(8)=(z-5)/(-5) .

Equation of a line passing through point (1,2,-4) and perpendicular to lines (x-8)/(3)=(y+19)/(-16)=(z-10)/(7)and(x-15)/(3)=(y-29)/(8)=(z-5)/(-5) is
