HEY THERE!!

AS WE KNOW cotx = base / perpendicular

and cscx = hypotenuse / perpendicular.

Here base = 4 and perpendicular = 3

So we have to find hypotenuse

Using trigonometry trick.

[tex]{H}^{2} = {B}^{2}+ {P}^{2}[/tex]
{H}^{2} = 16+ 9

taking squre root on both sides.
H = 5

now cscx = 5/3

SO YOUR ANSWER IS (D)5/3

HOPE IT HELPED YOU.
