Question

if 6cos square teta=4×1/2 then teta =

Answer 1

❤❤❤Hey!! ❤❤❤



Given

6 cos^2 theta =4 × 1 / 2 = 4 / 2 = 2

=> 6 cos^2 theta = 2

=> cos^2 theta = 2 / 6

=> cos^2 theta = 1 / 3

=> cos theta = 1 / √3

cos60° = 1 / √3

Hence, the value of theta = 60°.


Hope it helps!

Answer 2

Hi Mate !!


Here is your answer :


Solution :


6 Cos² Theta = 4 × 1/2


6 Cos² Theta = 4/2


6 Cos² Theta = 2


Cos² Theta = 2 / 6


Cos² Theta = 1/3


Cos² Theta = √1/3

Cos² Theta = 1 / √3


As we know , Cos60° = 1 / √3.


So,


Cos² 60° = 1/√3.


Here, 60 replace the theta...

So theta = 60°.


♥ Hope it helps you ♥
