1. Two of the main identities used in trigonometry for right triangles (Triangles that have an angle of 90°) are: Sine (Sin) and Cosine (Cos).
 Sin x°=Opposite/Hypotenuse
 Cos x°=Adjacent/Hypotenuse
 2. The inverse of Sinx° is Cosec x°, then:
 Cosec x°=1/Sin x°
 3. The inverse of Cos x° is Sec x°, then:
 Sec x°=1/Cos x°
 4. Keeping this on mind, you have:
 Cosc x°=Hypotenuse/Opposite
 Sec x°=Hypotenuse/Adjacent
 5. Therefore, the correct answer is:
 The third option: Cosec x°=Hypotenuse/Opposite.
