tolong ya , jangan ngasal, thank you
Penjelasan dengan langkah-langkah:
Kesebangunan
1. PQ/BC = AQ/AC
6/x = 5/(5+3)
6/x = 5/8
x = 8×6/5 = 9.6 cm
2. 8/(8+a) = 6/(6+4)
8/(8+a) = 6/10
8+a = 10×8/6
8 + a = 13.333
a = 5.3333 cm
3. AD/AB = DE/BC
6/10 = y/10
y = 6
AD/AB = AE/AC
6/10 = x/(x+2)
3/5 = x/(x+2)
3(x+2) = 5x
3x + 6 = 5x
6 = 2x
x = 3
