Question

solve : 2sin ^2theta =1/2 ;0 degree <theta<90 degree

​

Answer 1

Answer:

This answer is 30°.

Step by Step solution:

2sin^2 theta = 1/2

=> sin^2 theta = 1/2 divided by 2

=> sin^2 theta = 1/2 into 1/2

=> sin^2 theta = 1/4

=> sin theta = √1/4

=> sin theta = 1/2

=> sin theta = sin 30°. [ we know, sin 30° = 1/2

=> theta = 30°
