Question

if sinA=2sin²A then find the value of A

Answer 1

Answer:

30 degrees

Step-by-step explanation:

sin A=2sin²A

1=2sin A (cancel one sin A on both sides)

1/2=sin A

sin30 = sin A

thus A=30 degrees

Answer 2

Sin A = 2 Sin square A
Sin A = √2 Sin A X √2 Sin A
0 = 2 Sin A
1/2 = Sin A
Thus, Sin A = 30
