The angle between the lines \(x=\mathrm{y}, \mathrm{z}=0\) and \(\mathrm{y}=0, \mathrm{z}=0\) is
- A \(30^{\circ}\)
- B \(45^{\circ}\)
- C \(60^{\circ}\)
- D \(90^{\circ}\)
Answer & Solution
Correct Answer
(B) \(45^{\circ}\)
Step-by-step Solution
Detailed explanation
\( \text{Direction vector for } x=y, z=0 \text{ is } \vec{d_1} = \langle 1, 1, 0 \rangle \). \( \text{Direction vector for } y=0, z=0 \text{ is } \vec{d_2} = \langle 1, 0, 0 \rangle \).
