MCQ
Assertion (A) : In a right angled $\triangle ABC$, if $\angle ABC =90, AB =3 cm, BC =4 cm$, then $\sin A=\cos C$.
Reason (R) : $\frac{\sin \theta}{\cos \theta}=\tan \theta$ and $\sin \theta \quad \cos \theta=\cot \theta$.
Reason (R) : $\frac{\sin \theta}{\cos \theta}=\tan \theta$ and $\sin \theta \quad \cos \theta=\cot \theta$.
- ✓A is true, R is false
- BA is false, R is true
