X=6
First subtract 11 from both sides and you'll get 5x^2=180 then divide 180 by 5 which equals 36 you get x^2=36 find square root of 36 is 6
        
             
        
        
        
Step-by-step explanation:
= 5- 2 + 12 /4
= 5 -2 + 3
= 8- 2
= 6

It will be secx = 2 
 or, cosx = 1/2 
 or x = Π/3 , 5Π/3
