Assertion (A): If sin A =1/3(0^°< A <90^°), then the value of cos A is (2 √ 2)/3 Reason (R): For every angle θ, sin^2 θ+ cos^2 θ=1.

Assertion (A) : If $\displaystyle \sin \mathrm{A}=\frac{1}{3}\left(0^{\circ}<\mathrm{A}<90^{\circ}\right)$, then the value of $\displaystyle \cos \mathrm{A}$ is $\displaystyle \frac{2 \sqrt{2}}{3}$ Reason (R) : For every angle $\displaystyle \theta, \sin ^{2} \theta+\cos ^{2} \theta=1$.
