Questions
A line makes an angle of with the positive direction of axis and an angle of with the positive direction of axis. Then the angle that the line makes with the positive direction of axis, is
detailed solution
Correct option is A
If α,β,γ are the angles made by a line ‘L’ with the coordinate axes in the positive direction then cos2α+cos2β+cos2γ=1Given α=π3,γ=π4Hence, 14+cos2β+12=1⇒cosβ=12Therefore, β=π4Talk to our academic expert!
