Step 1: Recall the cosecant formula

FORMULA: If θ is one of the acute angles in a triangle, then the cosecant of

theta is the ratio of the  hypotenuse(hyp) to te opposite side(opp).

= \frac{hyp}{opp}

Step 2:  Plug in the relevant side lengths.

EXAMPLE: From triangle RTS

Opposite side to angle S = RT

Hyp = RS

⇒ \frac{RS}{RT}

⇒ \frac{13}{12}
