harap jawab ya besok di kumpulin yg no 4 5 6

Jawaban

4.
[tex] \frac{9}{9 + 3} = \frac{12}{12 + p} [/tex]
=
[tex] \frac{9}{12} = \frac{12}{12 + p} [/tex]
=9(12+p)=12,12 =12 x 12= 144

maka 144 -108=36 36:9=4 cm

5.
[tex] \frac{ \binom{6 + 4}{} }{x} = \frac{6}{3} [/tex]
[tex] \frac{10}{2} = 2[/tex]
[tex]10 \div 2 = 5cm[/tex]

6. nilai X
AE/EC = AD /DB
x/2 = 6/4
4 x =12
x = 12/4 =3

nilai Y
AD/AB = DE /BC
6/10 = y/10
60=10y
=60/10=y

6=y=y6
