Natural numbers and while numbers refer to positive numbers, so -3 cannot be either of those.
        
             
        
        
        
Answer:
10) 9x - 2° = 5x + 54° (corresponding angles are equal)
9x - 5x = 54 + 2
4x = 56
x = 56/4
x = 14°
10y + 6° = 9x - 2° (linear pair)
10y + 6° = 9(14)° - 2°
10y + 6° = 126° - 2°
10y + 6° = 124°
10y = 124° - 6°
10y = 118
y = 118/10

Dividing fractions is the same thing as multiplying by the reciprocal
3/4 x 24/1 = 18
        
                    
             
        
        
        
Answer:
h = V/y^2
Step-by-step explanation:
The volume of a right pyramid is given by the expression = Area of base × height.
Area of base = Area of square at the base 
= y × y = y^2.
Now, we substitute these values: 
V = y^2 × height
height = V/y^2
