HEYA FRIEND,☺️

HERE IS YOUR ANSWER,

1 + 2 sin a cos a - 2 sin a - cos a = 0
or, 2 sin a cos a - cos a + 1 - 2 sin a = 0
or, cos a(2 sin a - 1) - 1 (2 sin a - 1) = 0
or, (cos a - 1) (2 sin a - 1) = 0

cos a - 1 = 0 2 sin a - 1 = 0
cos a = 1 sin a = 1/2
cos a = cos 0° sin a = sin 30°
a = 0° a = 30°

HOPE IT HELPS UH!!☺️☺️
