Question

2 cos 2θ = √3 then the value of θ​

Answer 1

Answer:

theta =15⁰

Step-by-step explanation:

cos2∅=√3/2

cos30⁰=√3/2

so ∅=15⁰

Answer 2

Answer:

θ = 15 °

Step-by-step explanation:

2 cos 2θ = √3

cos2θ = √3/2

we know what

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

$\cos^{ - 1}( \frac{ \sqrt{3} }{2} ) = \frac{\pi}{6}$

2θ =

$\frac{\pi}{6}$

$θ = \frac{\pi}{12}$

θ = 15°
