tolong ya mksh no 1 & 2

sdt ADE = sdt ACB
sdt DAE = sdt BAC
AB= AE
maka sebangun
8/20 = x/30
x = 12 = DE
12/x = 8/20
x= 30 = ac

6/12 = x/16-x
12x = 96 - 6x
18x = 96
x = 5 1/3 = AE

6/12 = x/20-x
12x = 120 - 6x
18x = 120
x = 6 2/3 = BE

Maaf hanya bisa menjawab itu aja, semoga membantu

Maaf juga kalau salah
