Sir in question number 3, how do we know that the angle is 30 degrees?

[chandra]

Please make videos on vector algebra sir

[aditi]

In question no one how can we say that the equation has exactly n roots...no root will be repeated

[mahfoozalam]

Your question no. 3 is wrong!!...As you don't know whether it is a equilateral triangle or not..Rather we first need to find the angles using simple geometry then, finally we will get to know that it is equilateral.
