Question #cbd0e

Answer 1

see explanation.

Explanation:

`six (x) = 1/2`
`x = pi/6 or 30^o`

since `sin (x)` is a positive value, it lie in 1st and 2nd quadrant only.

Therefore,

1st quadrant,
`x=pi/6 or 30^0`
`x=(2pi+1/6 pi)=13/6 pi or (360^o + 30^0) = 390^0`
In 1st quadrant, `x = pi /6 and 13/6 pi`

2nd quadrant,
`x=5/6 pi or (180^o-30^0) = 150^o`
`x=(2 pi+5/6 pi) = 17/6 pi or (360^o + 150^0) = 510^o`
In 2nd quadrant, `x=5/6 pi and 17/6 pi`
