Question

ayuden me a este problema en serio no le entiedo

Las medidas de AC y BD suman 60 cm. Si AM mide 3/10 de dicha suma , calcula:
AM = ___________ DM=___________ CM=___________ BM=____________
AC=____________ BD=___________

Answer 1

AC + BD = 60 cm

AM = 3 (60) / 10

AM = 18 cm

CM = 18 cm

AC = AM + CM = 18 + 18

AC = 36 cm

AC + BD = 60 cm

36 + BD = 60

BD = 60 - 36

BD = 24 cm

BD = BM + DM

24 = BM + BM

24 = 2BM

12 = BM

BM = 12 cm

DM = 12 cm

AB + BC + CD + AD = 80 cm

CD = 3AD

AB = CD,  BC = AD

AB = 3AD

3AD + AD + 3AD + AD = 80

8AD = 80

AD = 10 cm

AB = 3AD = 3(10)

AB = 30 cm

BC = 10 cm

CD = 3AD = 3(10)

CD = 30 cm
