Answer:
20
Step-by-step explanation:
The two given and marked angles add up to 90.
A = x
B = 3x + 10
A + B = 90          Substitute for A and B. A and B are just letters I gave things.
 
x + 3x + 10 = 90        Combine the left
4x + 10 = 90              Subtract 10 from both sides.
4x +10-10 = 90-10     Combine
4x = 80                      Divide by 4
4x/4=80/4
x = 20
 
        
                    
             
        
        
        
There are 12 inches in one foot. 120 x 12 = 1,440 inches. The correct ratio to be placed is the 5th one (aka 12 inches over 1 foot).
