Question

Find the ratio 2sinA:sin2A when A=30°.​

Answer 1

Step-by-step explanation:

2 sin 30:sin2(30)

2*1/2 : sin 60

1:√3/2

Answer 2

Answer:

$\sin(2 \times 30) =2 \sin(30 \times \cos(30) \\ \sin(6 0) = 2( \frac{1}{2} ) \times \sqrt{ \frac{3}{2} } \\ \sqrt{ \frac{3}{2} } = \sqrt{ \frac{3}{2} } \\ \\ hence \: verified \: \\ hope \: this \: helps \: you \: \\ mark \: me \: as \: the \: brainliest$
