Given: Volume of brains in cubic centimeters.
Because it is talking about volume it is something you can ordered, difference can be found and are meaningful. There is also a natural starting zero point because something can have 0 volume. Like an empty cup. It has no water in it for volume.
Answer:
D. The ratio level of measurement is most appropriate because the data can be ordered, differences can be found and are meaningful, and there is a natural starting zero point
 
        
             
        
        
        
Answer:  True
One angle of a right triangle  = 90°
Let x =  the acute angle of one angle.
Let y =  the angle of the other angle.
Because the sum of angles in a triangle is 180°,
x + y + 90 = 180
x + y = 90
y = 90 - x
Therefore the angles for each of the two triangles are
x, 90° - x, 90°.
The two triangles are therefore similar because of AAA (Angle, Angle, Angle).
