AP EAMCET · Maths · Three Dimensional Geometry
The angle between a line with direction ratios and the line joining the points and is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
It is given that the direction ratios of first-line are 2,2,1 and the direction ratios of second-line joining the points (3,1,4) and (7,2,12) are, (7-3,2-1,12-4) (4,1,8) The angle between the two lines is, cosθ=a1a2+b1b2+c1c2a12+b12+c12a22+b22+c22…
