31:05 sir how come it's 90 there is no data of 90 , 91 is there

[@TendingtoInfinity]

You can take any value instead of 90, that's just to minimize the values of xi.

[@ArjunDutta-dm3uy]

Sir oikhne median tow 94 asche

[@ArjunDutta-dm3uy]

Sir 3rd question ar calculation ta buglom na

[@annann256]

The formula of tantheta=|m2-m1|÷(1+m1m2) Now put the values of m2 and m1, it's gonna work.
