Step-by-step explanation:
1/sin theta + cos theta/sin theta=5/3
1+cos theta/sin theta=5/3
2cos^2 (theta/2)/2sin theta/2.cos theta/2=5/3
cos theta/2 / sin theta/2=5/3
cot theta/2=5/3
let theta/2 be x
cot x=5/3
means we got opposite and adjacent side length....so lets calculate the value of hypotenuse.
hyp=(5^2-3^2)^1/2
=4
therefore sin x =3/4....x=48.59
ie, sin theta/2 is 3/4....theta=97.18
therefore sin theta is approximately equal to one
sin 97.18 approximately equal to one.
