A) \[-\frac{4}{3}\]
B) \[\frac{3}{4}\]
C) \[-\frac{3}{5}\]
D) \[\frac{5}{3}\]
Correct Answer: D
Solution :
Since, the angle between the line and plane is a complementary angle between the line and normal to the plane. Note The angle between a lineand plane is given by Alternate Solution Direction ratios of line normal are and direction ratios of a plane are Since, \[\sin \theta =\,\frac{{{a}_{1}}{{a}_{2}}+{{b}_{1}}{{b}_{2}}\,+{{c}_{1}}{{c}_{2}}}{\sqrt{a_{1}^{2}+b_{1}^{2}+c_{1}^{2}\,\sqrt{a_{2}^{2}\,+b_{2}^{2}\,+c_{2}^{2}}}}\]You need to login to perform this action.
