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.
