Question

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

Answer 1

Answer:

4A=π-2A

6A=π

A=π\6= 30 Degree

so,sin(30)=1/2

Answer 2

Solution :-

Given ,

=> 4A = π - 2A

=> SinA = ?

By simplifying the given equation , & substituting π = 180°

➜ 4A = 180° - 2A

➜ 6A = 180°

➜ A = 180°/6

➜ A = 30°

Now substituting the value of angle A

☞ sinA

☞ sin(30°)

☞ 1/2

Hence the value of sinA is 1/2
