Question

Me podrían ayudar a resolver este ejercicios.

Answer 1

1)

AC / AB = A 'C' / A 'B'

13/ 15 = 52/65

AC / CB = A 'C' / C 'B'

13/9 = 52/36

0.86 = 0.8

1.44 = 1.44

No son semejantes

2)

AC / AB = A 'C' / A 'B'

24/28 = 156/182

AC / CB = A 'C' / C 'B'

24/18 = 156/117

0.85 = 0.85

1.34 = 1.34

Si son semejantes

3)

AC / AB = A 'C' / A 'B'

16/ 18 = 57.6/64.8

AC / CB = A 'C' / C 'B'

16/9 = 57.6/32.4

0.89 = 0.89

1.78 = 1.78

Si son semejantes

4)

AC / AB = A 'C' / A 'B'

16/20 = y/153

y = 153 × 16/20 = 122.4

16/20 = 122.4/153

AC / CB = A 'C' / C 'B'

16/12 = y/x

16/12 = 122.4/x

x = 12 × 122.4/16 = 91.8

0.8 = 0.8

1.34 = 1.34

Si son semejantes.

5)

AC / AB = A 'C' / A 'B'

32/36 = 204.8/y

y = 36 × 204.8 /32 = 230.4

32/36 = 204.8/230.4

AC / CB = A 'C' / C 'B'

32/x = 204.8/120

x = 120 × 32/204.8 = 187.5

32/187.5 = 204.8/120

0.89 = 0.89

0.1706 = 0.1706

Si son semejantes.
