Answer:
38 > 36
it is true it shows that 38 is greater than 36
Answer:
Option c) Transitivity
Step-by-step explanation:
We are given the following information in the question:
If A exceeds B in some property and B exceeds C, then A must also exceed C.
We have to define the property shown by A,B and C.
Transitivity:
- It is a mathematical property which states that between three numbers if first and second share the property, second and third share the property, then according to transitive property, the property holds between first and third as well.
Thus, A, B and C here shows the transitive property.
The correct answer is
Option c) Transitivity

Answer:
Only A is not Pythagorean Identity.
Step-by-step explanation:
Let us draw a unit circle as shown in the attached figure.
In the given figure, let us apply Pythagorean theorem, which is given by
![x^2+y^2=z^2\\\\x=\sin\theta,y=\cos\theta,z=1\\\\\sin^2\theta+\cos^2\theta=1^2\\\\\sin^2\theta+\cos^2\theta=1........(C)](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3Dz%5E2%5C%5C%5C%5Cx%3D%5Csin%5Ctheta%2Cy%3D%5Ccos%5Ctheta%2Cz%3D1%5C%5C%5C%5C%5Csin%5E2%5Ctheta%2B%5Ccos%5E2%5Ctheta%3D1%5E2%5C%5C%5C%5C%5Csin%5E2%5Ctheta%2B%5Ccos%5E2%5Ctheta%3D1........%28C%29)
Divide both sides by ![\sin^2\theta](https://tex.z-dn.net/?f=%5Csin%5E2%5Ctheta)
![\frac{\sin^2\theta}{\sin^2\theta}+\frac{\cos^2\theta}{\sin^2\theta}=\frac{1}{\sin^2\theta}\\\\1+\cot^2\theta=\csc^2\theta.......(B)](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csin%5E2%5Ctheta%7D%7B%5Csin%5E2%5Ctheta%7D%2B%5Cfrac%7B%5Ccos%5E2%5Ctheta%7D%7B%5Csin%5E2%5Ctheta%7D%3D%5Cfrac%7B1%7D%7B%5Csin%5E2%5Ctheta%7D%5C%5C%5C%5C1%2B%5Ccot%5E2%5Ctheta%3D%5Ccsc%5E2%5Ctheta.......%28B%29)
Divide both side of identity C by ![\sin^2\theta](https://tex.z-dn.net/?f=%5Csin%5E2%5Ctheta)
![\frac{\sin^2\theta}{\cos^2\theta}+\frac{\cos^2\theta}{\cos^2\theta}=\frac{1}{\cos^2\theta}\\\\\tan^2\theta+1=\sec^2\theta.......(D)](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csin%5E2%5Ctheta%7D%7B%5Ccos%5E2%5Ctheta%7D%2B%5Cfrac%7B%5Ccos%5E2%5Ctheta%7D%7B%5Ccos%5E2%5Ctheta%7D%3D%5Cfrac%7B1%7D%7B%5Ccos%5E2%5Ctheta%7D%5C%5C%5C%5C%5Ctan%5E2%5Ctheta%2B1%3D%5Csec%5E2%5Ctheta.......%28D%29)
Therefore, only A is not Pythagorean Identity.
