Hello you answer will be...... -x+4 
let me know if I’m right
        
             
        
        
        
Here we are finding x, given the angle and adjacent side. To find x we will use the function cos as cos = a/h.
So let's do cos(35°) = 15cm / x
cos(35°) = 0.8 (1 dp)
x = 15 cm / cos(35°)
x = 18.3 cm (1 dp)
 
        
             
        
        
        
The answer is 15,000,000,000,000
