Answer:
65/63
Explanation:
Cosecant is the inverse of sine. Given the triangle NOP with <P = 90° and NP = 16, ON = 65, and PO = 63
Considering the angle N using the notation
SOH
where O is the opposite side and H is the hypotenuse
The opposite side of the triangle is PO = 63 while the hypotenuse side is ON = 65
hence
Sine N = 63/65
since Cosecant N = 1/Sine N
Cosecant N = 65/63
