The three missing lengths are the left hypotenuse, x, the middle altitude, y, and the right hypotenuse, z.
9/y = y/16
y^2 = 9 * 16
y^2 = 144
y = 12
9^2 + 12^2 = x^2
x^2 = 225
x = 15
12^2 + 16^2 = z^2
z^2 = 400
z = 20
From left to right, the sides measure 15, 12, and 20 units.
 
        
                    
             
        
        
        
if itis perimeter add all sides
if it is área multiply
 
        
             
        
        
        
N would equal 45° since the tiny square means its 90°. 90-45=45.
        
                    
             
        
        
        
Answer:
it would be 32
Step-by-step explanation:
you would add them all up then divide it by five 
 
        
                    
             
        
        
        
X + x + 165 = 1315
2x + 165 = 1315
subtract 165 from both sides
2x = 1150
divide both sides by 2
x = 575
January 575
February 575 + 165 = 740
