☆ Now Let's find value of sin A, cos A and tan A,
⠀⠀⠀
- sin A = Perpendicular/Hypotenus =
⠀⠀⠀
- cos A = Base/Hypotenus =
⠀⠀⠀
- tan A = Perpendicular/Base =

Given:
To find:
The value of x.
Solution:
We have,
To find the value of x, we need to isolate x on one side.
Subtract 2b from both sides.
Divide both sides by -3. On multiplying or dividing an inequality by a negative number, we need to change the sign of inequality.
The required inequality for x is .
Therefore, the correct option is A.
