Given:

Convert radian to degree

[tex]=\frac{180}{\pi}[/tex]

Find-:

What is always happen with pis

Explanation-:

If the angle is radian

Let angle is:

[tex]=x\pi[/tex]

So,

Angle in degree is:

[tex]\begin{gathered} =x\pi\times\frac{180}{\pi} \\ \\ =180x \end{gathered}[/tex]

So, they will cancel out.
