Answer:
3/4
Step-by-step explanation:
Correct Question :-
If sinθ = -3/5 and 180°< θ < 270° then tanθ = ?
Given,
sinθ = -3/5
180°< θ < 270°
To Find :-
Value of tanθ.
Solution :-
As :- 180°< θ < 270°
→ θ is in 3rd quadrant.
In 3rd quadrant "sin" is negative and "tan" is positive.
So the value of tanθ should be positive.
→ 3 = opposite side[ As sin is negative we should not consider its sign]
5 = hypotenuse
Applying pythagoras theorem :-
Adjacent side = 4
tanθ = 3/4
