In this question, the provided value is

*

And we have to discover the value of sin theta and also tan theta wherein theta is in very first quadrant .

You are watching: If , which of the following represents approximate values of and , for ?

And in an initial quadrant, all are hopeful .

Now we use the formula, i beg your pardon is

*

And tan theta is the proportion of sin theta and cos theta, that is

*

So the correct choice is B .



The correct alternative is B) ; .

Step-by-step explanation:

Consider the provided value the trigonometry function.

Use the identity:

*

*

*

Now substitute

*

Hence, the value of .

Now, use the identification

*

Substitute the corresponding values.

The finish question in the fastened figurewe know that 0° soangle theta belong to the very first quadrantsin theta and also cos theta room positivecos theta=0.3090cos²theta+sin²theta=1step 1find sin thetasin²theta=1-cos²theta------> 1-(0.3090)²-----> sin²theta=0.904519sin theta=√0.904519------> sin theta=0.9511the answer component a) issin theta=0.9511step 2find tan thetatan theta=sin theta/cos theta-----> tan theta=0.9511/0.3090tan theta=3.0780the answer part b) istan theta=3.0780the last answer issin theta=0.9511tan theta=3.0780

If cos theta=0.3090, i beg your pardon of the following represents approximate worths of sin theta and also tan theta, for 0degrees
