Answer: B.
.
Step-by-step explanation:
- In a right triangle, the ratios of its sides are called trigonometric ratios.
- The three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan).
We have given ,
.
Then, ![\cos\theta =\sqrt{1-\sin^2\theta}\ [\because\ \sin^2A+\cos^2A=1]](https://tex.z-dn.net/?f=%5Ccos%5Ctheta%20%3D%5Csqrt%7B1-%5Csin%5E2%5Ctheta%7D%5C%20%5B%5Cbecause%5C%20%5Csin%5E2A%2B%5Ccos%5E2A%3D1%5D)
Put value of
, we get


Now , as we know , 
Hence, the correct option is B.
