Suppose the sides of the big triangle are called m, x and 12+4=16. We have that the big triangle and the small triangle to the right of the shape (sides x,y,12) are similar. We can take then the ratios of correponding sides and know that they will be equal. Thus, we have that 4/y=y/12. Hence, y*y=48. Thus y=

(-4, 3, 10). I'm not really sure tho
8 alligator because is u divide 48/5 you get 40 and the remaining that r awake is 8
Well lets see..
factors of 28 are 1, 2, 4, 7, 14, 28
factors of 56 are 1, 2, 4, 7, 8, 14, 28, 56
factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42,84
as u can see, 28 is the highest in all of them so the greatest common factor is 28. hope this helps!
