B= 60 
To find b you must do the pythagorean theorem because it is a right triangle
65^2 - 25^2=b^2
3600=b^2
60=b
x= 18 
To find x you must know that a triangle is made up of 180 degrees.
x= 180-(72+90)
x=180-162
x=18
hope this helped :)
        
             
        
        
        
Answer:
6√3
Step-by-step explanation:
Use the sin formula, which is sin = opp / hyp
sin 60 = x / 12
x = 12 sin 60 
x = 6√3 
 
        
             
        
        
        
The exponent on the P will be 5
        
                    
             
        
        
        
Step-by-step explanation:
6228 = 6000 + 200 + 20 + 8.
The 2s in 6228 represent 200 ; 20.
