Question

Solve 4 square root of 3 = 8cos

Answer 1

Therefore
`\theta = 30^\circ`

Explanation:

Given,

`4√(3 ) =8 cos \theta`

`\Leftrightarrow cos \theta =(4√(3) )/(8)`

`\Leftrightarrow cos \theta =(√(3) )/(2)`

`\Leftrightarrow cos \theta =cos 30^\circ`

`\Leftrightarrow \theta = 30^\circ`

Therefore
`\theta = 30^\circ`
