In this question, the given value is
And we have to find the value of sin theta and tan theta where theta is in first quadrant .
And in first quadrant, all are positive .
Now we use the formula, which is
And tan theta is the ratio of sin theta and cos theta, that is
So the correct option is B .
Answer:
I'm not sure how you want us to answer this. I attached an image of where it is but otherwise it's in quadant I which is the top right one.
Hope this helps!

Answer:
56
Step-by-step explanation:
The n th term of an AP is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₆ = 17 and a₁₃ = 38, then
a₁ + 5d = 17 → (1)
a₁ + 12d = 38 → (2)
Subtract (1) from (2) term by term to eliminate a₁
7d = 21 ( divide both sides by 7 )
d = 3
Substitute d = 3 into (1) and evaluate for a₁
a₁ + 5(3) = 17
a₁ + 15 = 17 ( subtract 15 from both sides )
a₁ = 2
Thus
= 2 + (18 × 3) = 2 + 54 = 56
