no 1 & 2 .tolong pakai caranya:)

1. Dik : panjang AC/CA = 25cm
panjang AD/DA = 9cm
panjang CD = panjang AC - panjang AD
= 25cm - 9cm
= 16cm
Dit: a. panjang BD
b. panjang BC
jwb:
a. BD² = CD × DA
BD² = 16 × 9
BD² = 144cm
BD = √144cm
BD = 12cm
b. BC² = CD² × CA²
BC² = 16cm×25cm
BC² = 400cm
BC = √400cm
BC = 20cm
2. a. <P = <P = 90°
<B = <D = 90°
<A = <C = 90°
karena sudut - sudut yang bersesuaian sama besar
b. AB/CD = AP/PC = BP/PD
C.CP/PB = CD/AB
CP/9 = 20/8
CP×8 = 9×20
CP×8 = 180
CP = 180/8
CP = 22.5cm
maaf kalau salah,semoga bermanfaat!
