Which equation is correct
Sergeeva-Olga [200]
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.
