 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.
