tolong yang ditentukan x dan y besok di kumpul​

segitiga AED dan segitiga ACB sebangun, maka perbandingan sisi - sisinya :

AD / AB = AE / AC = ED / CB

jawab :

mencari nilai x :

AE / AC = AD / AB

x / (x + 2) = 6 / (6 + 4)

x / (x + 2) = 6 / 10

x / (x + 2) = 3 / 5

5x = 3(x + 2)

5x = 3x + 6

2x = 6

x = 3cm

mencari nilai y :

ED / CB = AD / AB

y / 10 = 6 / (6 + 4)

y / 10 = 6 / 10

y / 10 = 3 / 5

5y = 30

y = 6cm
