Question

If 4A = π - 2A , find the value of sin A.​

Answer 1

Answer:

sin A=$\frac{1}{2}$

Step-by-step explanation:

4A=π-2A

4A+2A=π

6A=π

A=π×$\frac{1}{6}$

A=$\frac{\pi }{6}$

A is in radian so we will convert it into degree to make it easy to understand,

1 rad=$\frac{180}{\pi }$ degree

$\frac{\pi }{6}$ rad=$\frac{\pi }{6}$×$\frac{180}{\pi }$=30°

sin(30°)=$\frac{1}{2}$

here is the required answer hope it will help you.
