hey
easy question.
2sin²x=1/2 } (given)
so .
sin²x=1/2×2
sinx=√1/4
sinx=1/2 {as you know bro sin30°=1/2}
so..sinx=sin30°
(sin ,sin cancelled of both side )
then
x=30° Ans. ..
hope it helps you

2(sin^2x) = 1/2
(sin x)^2 = 1/4
sin x = +1/2 and -1/2. (We can't take (-1/2) as x lies b/w 0 and 90 degrees)
x = 30 degrees.

it is given that 0 less than or equal to x less than or equal to 90
so x is between 0 and 90
we cannot take x=330
Yeah. You're right. I didn't see that.
