Question

Encuentra el valor de x en los siguientes triángulos ​

Answer 1

Respuesta:

Explicación paso a paso:

1. x/5 = 6/(6 + 3) = 6/9 = 2/3

  x = 5 . (2/3) = 10/3 = 3.33....

--------------------------------------------------------

2. 20/(x + 20 ) = 15/(15 + 10) = 15/25 = 3/5

  x + 20 = (5 . 20)/3 = 33.33...

  x = 33.33... - 20 = 13.33...

--------------------------------------------------------

3. 8/(x + 8) = 10/ 14

  x + 8 = (8 . 14)/10 = 11.2

  x = 11.2 - 8 = 3.2

--------------------------------------------------------

4. 8/(x + 8) = 10/ 16 = 5/8

  x + 8 = (8 . 8)/5 = 64.5 = 12.8

  x = 12.8 - 8 = 4.8

--------------------------------------------------------

5. 16/(16 + 8 ) = x/10

  x  = (16 . 10)/24 = 20/3 = 6.66...

  x = 6.66.....
