Question

Tolong jawab soal nomer 23,24,dan 25
beserta caranya. please....

Answer 1

23. PQ = 12x6+27x4 dibagi hasil 6 +4
= 180/10= 18 cm

Answer 2

23. Dc x Qb + Ab x Cd / Cb =
=12 x 6 + 27 x 4 / 10
= 72 + 108 / 10
= 180 / 10 = 18

24. 20/26 = 30/33 + x
20/26 dibagi 2
10/13 = 30/33 + x
dikali silang
330 + 10x = 390
10x = 390-330
10x = 60
x = 6

25. 4x + 18 + 2x = 180
6x + 18 = 180
6x = 180-18
6x = 162
x = 162/6
x = 27

sudutPQR = 4 x 27 + 18
= 108 + 18
= 126

maaf jika salah
