Question

Find the ratios of :
i) 2 sin 30° : Sin 60°
ii) 2 cos 30° : cos 60°​

Answer 1

Answer:

$(i) \: \: \frac{2 \times \sin(30) }{ \sin(60) } = \frac{2 \times \frac{1}{2} }{ \frac{ \sqrt{3} }{2} } = \frac{2}{ \sqrt{3} } \\ (ii) \: \frac{2 \times \cos(30) }{ \cos(60) } = \frac{2 \times \frac{ \sqrt{3} }{2} }{ \frac{1}{2} } = 2 \sqrt{3}$
