Question

AYUDAAAAAAAA PORFA:)

Answer 1

Ejercicio 2!

- AB = x

- AC = x + 7 = a

- CD = x

- Sumamos todo!

AB + BC + CD + DE

x + 7 + x + 5 = 50

2x + 12 = 50

2x = 38

x = 19

Entonces AB = 19

Ejercicio 3!

- BC = 16 = 2b

16 = 2b

8 = b

- AD = a + b = 12

a + b = 12

a + 8 = 12

a = 4

- Finalmente Hallamos AC :

a + b + b

4 + 8 + 8

20

AC = 20
