sleepyjess · Answer

I got $\dfrac{210\pi}{80}$ simplified to $\dfrac{21\pi}{8}$

mayankdevnani · Answer

Remember :-
When you convert degrees into radians ,we use this
suppose `x` be a degree :-
$$\large \bf Radian=\frac{\pi}{180}\times x$$

mayankdevnani · Answer

so,for 210 degrees :-
$$\large \bf Radians=\frac{\pi}{180} \times 210$$

now simplify it !

@sleepyjess i hope you understand !

sleepyjess · Answer

OOOHHHHHHH i put 80 and not 180

mayankdevnani · Answer
