QUESTION #51 Shortest Distance Between Lines
Let the values of λ for which the shortest distance between the lines (x - 1)/(2) = (y - 2)/(3) = (z - 3)/(4) (x - λ)/(3) = (y - 4)/(4) = (z - 5)/(5) is 1√(6) be λ₁ and λ₂. Then the radius of the circle passing through the points (0, 0), (λ₁, λ₂) and (λ₂, λ₁) is

QUESTION #73 Area of Triangle Formed by Intersecting Lines
Let the area of the triangle formed by the lines x + 2 = y - 1 = z, (x - 3)/(5) = (y)/(-1) = (z - 1)/(1) and x-3 = y - 33 = z - 21 be A. Then A² is equal to
