Please see here: 
The root $x=0.797$ lies in $(0,\frac {\pi}{2}) $ verifying the result. Hope it helps.

The root may be found with Newton's method:
$$0=x+2-2\csc(x)$$
$$x_{n+1}=x_n-\frac{x_n+2-2\csc(x_n)}{1+2\csc(x_n)\cot(x_n)}$$
With $x_0=0.8$, we get
$x_1=0.7967677637$
$x_2=0.7967790659$
$x_3=0.7967790660$
Which is the solution out ten places.
