Question

Ada yang tau gak nomor satu cara nya gimana? please....

Answer 1

DE/AB = CD/CA
12/18 = 8/(8+DA)
2/3 = 8/(8+DA)
*2 dan 8 sama sama dibagi 2
1/3 = 4/(8+DA)
8+DA = 3×4
DA = 12 - 8
DA = 4

CA = DA + CD
= 4 + 8 = 12

CD/DA = CE/EB
8/4 = CE/6
*8 dan 4 sama sama dibagi 4
2 = CE / 6
CE = 6x2
CE = 12

jadi AD = 4, CA = 12, CE = 12..
mohon di check lagi, maaf kalau saya salah
