What is tanθ?
1) (4/3)
2) -(sqrt(7)/4)
3) (sqrt(7)/3)
4) -(sqrt(7)/3)

You can put this solution on YOUR website! If sinθ = (sqrt(7)/4) and, cos < 0.
What is tanθ?
---
Note: Since sin is positive and cos is negative, theta is in QII
-----------------
By definition sin = y/4, so y = sqrt(7), r = 4
---
The x = -sqrt[16-7] = -sqrt(9) = -3
-------
Ans: tan(t) = y/x = -sqrt(7)/3
-------------------------------
