A triangle is rotated around N to give the primed version.
A. Same shape and size -- TRUE.  Rotation doesn't change shape or size.
B. Corresponding points are equidistant to N.  That's TRUE, each point is rotated around N to get its corresponding point, which will be the same distance from N.
C. DN=D'N.  TRUE, just an example of corresponding points.
D. Corresponding side lengths unequal, FALSE.  Rotation doesn't change lengths.
 
        
             
        
        
        
Answer:
216 cm³
Step-by-step explanation:
1/3x + 63 = 5/8x
subtract 1/3x from each side; (1/3x = 8/24x  and  5/8x = 15/24x)
63 = 7/24x
7x = 63(24)
7x = 1512
x = 216
 
        
             
        
        
        
Answer:
The ladder is 4.86 foot from the base of the wall . 
Step-by-step explanation:
Given as :
The length of the ladder = 28 ft
The ladder makes angle of 80° with the ground
Let The distance of the ladder from the foot of the wall = x ft
Now, From Triangle BAC
Cos angle = 
I.e Cos 80° = 
Or, 0.1736 =  
Or, x = 0.1736 × 28
∴  x = 4.86 foot
So, The distance of ladder from wall base = x =  4.86 foot
Hence The ladder is 4.86 foot from the base of the wall . Answer
