Answer:
- D. No, they are not similar.
Step-by-step explanation:
<u>Check the ratio of the two given sides:</u>
- MV/VT = 21/49 = 3/7
- LV/VU = 8/28 = 2/7
Ratios are different so the triangles are not similar
Correct choice is D
 
        
             
        
        
        
20 bicycles each of 2 wheels 
So 20 x 2 = 40 wheels
10 cars each of 4 wheels
So 10 x 4 = 40 wheels
Total = 40 + 40
 = 80 wheels
