Answer:
θ = 30 (For 10th class)
θ = 150, 210, 330 (For 11th class)
Step-by-step explanation:
3tanθ =cotθ
3tanθ = 1/tanθ
3tan²θ=1
tanθ= +-(1/√(3))
in 1st quadrant tanθ= 1/√(3) θ= 30 [For 10th class]
in 2nd quadrant tanθ= -1/√(3) θ= 150 [For 11th class]
in 3rd quadrant tanθ= 1/√(3) θ= 210 [For 11th class]
in 4th quadrant tanθ= -1√(3) θ= 330 [For 11th class]
