Step-by-step explanation:
2sin(x)cos(x) - sin(x) + 2cos(x)-1= 0
<=> sinx( 2cosx -1) + ( 2cosx -1) =0
<=> (sinx +1) + ( 2cosx-1)=0
<=> sinx=-1 or cosx= 1/2
+) sinx=1 => x= pi/2 + k×2pi
+)cosx=1/2 => x= pi/3+ k×2pi or x=-pi/3 + k×2pi
x€ [0,2pi] => x= pi/2, pi/3.
The answer is 29.
I hope it helps if not pls let me know
1.) you have to subtract 6 from both sides to get rid of 6
2.) 11 minus 6 is 5
3). this leaves you with y = 5
It is c.it is actually 1.548 but you round it so....
