Question

2 cos theta is equal to root 3 then sin theta is equal to​

Answer 1

2cosθ=√3

cosθ=√3÷2

cos of 30 degrees gives √3/2

so sin of 30 degrees

sin30=1/2

Answer 2

Step-by-step explanation:

$2 \cos(theta) = \sqrt{3}$

$\cos(theta) = \frac{ \sqrt{3} }{2} = \cos(30)$

theta=30°

$\sin(theta) = \sin(30) = \frac{1}{2}$
