Answer:

Option C. \frac{1}{4}\sqrt{15}

Step-by-step explanation:

It is given in the question

sin\theta =\frac{1}{4}

and we have to calculate the value of cos\theta

since we know that

cos\theta =\pm \sqrt{1-sin^{2}\theta }

It has been given in the question that tan\theta >0 means sine and cosine both are of same sign so we will positive sign of cosine.

Now by putting the value of sin\theta in the formula given

cos\theta =\sqrt{1-sin^{2}\theta}=\sqrt{1-(\frac{1}{4})^{2}}=\sqrt{\frac{16-1}{16}}=\sqrt{\frac{15}{16}}=\frac{1}{4}\sqrt{15}

Therefore option C. \frac{1}{4}\sqrt{15} is the answer.
