Jawab tolongg :'( Diketahui jajaran genjang ABCD dengan panjang AB = (5x - 18)cm, CD = (3X + 10)cm, dan sudutA : sudutD = 7 : 5. Hitunglah: A. Nilai X B. Panjang AB C. Besar sudutA

A. x = 5x-18 = 3x + 10 5x-3x = 10 + 18 2x = 28 x = x = 14 b. Ab = 5x - 18 = 5.14 - 18 = 70 -18 = 52 c. A = x 180 =
5x-3x = 10 + 18
2x = 28
x =
x = 14
b. Ab = 5x - 18 = 5.14 - 18 = 70 -18 = 52
c. A = x 180 =
Maaf klo slah:)
