Answer:
30°
Step-by-step explanation:
sin²X - 5sinX + 3 = 1× cos²X
sin²X - 5sinX +3 = cos²X
sin²X - 5sinX + 3= 1- sin²X
sin²X - 5sinX + 3-1 +sin²X
2sin²X -5sinX +2 = 0
2sin²X - 4sinX - sinX +2 =0
2sinX(sinX - 2) - 1( sinX- 2) =0
(2sinX-1) (sinX- 2) =0
2sinX-1=0 & sinX-2= 0
sinX = 1/2 & sinX= 2
sinX= sin30° & sinX is not equal to 2
therefore X= 30°
You can write thita in the place of X
