why
according to the question we have to not use the trigonometric table but we have used it at the place of tan60°
Wait for some time
In this question, it is saying that without using trigonometry ratios,we have to solve.It means we should not use trigonometry ratios of cosec39,tan17,tan73,etc.In case,of tan 60,we learn it
we can use sin tan cos of angles 15 30 45 60 and 90
