Question

ayúdame no entiendo con su procedimiento ​

Answer 1

Respuesta:

1) BC = 3a = 3(10) = 30

AD = 60

a + 3a +2a = 60

6a =60

a = 10

2) AD = 10 +24 = 34

CD = a

AB = 10

BC = X

X + a = 24

x = 24 - a

10 + x = a

10 + 24 - a = a

34 = 2a

17 = a

X + a = 24

X + 17 = 24

X = 7

3) PQ = PM + MQ

PQ = 6 + 6 = 12

QR = PQ

12 = 12

PR = PQ + QR

PR = 12 + 12 = 24

4) AD = 24

AB = BD

X = X

AD = AB + BD

24 = 2x

X = 12

BD = 4 (CD)

12 = 4(CD)

3 = CD
