Answer 1

1. panjang AC = 13

2


3 PQ= 5

Answer 2

1. a)AC^2 = BC^2 + AB^2
AC^2 = 5^2 + 12^2
AC^2 = 25 + 144
AC^2 = 169
AC = 13cm
b) kel = ab + bc + ac
kel = 12cm + 5cm + 13cm
kel = 30cm

2. PR^2 = QR^2 - PQ^2
PR^2 = 34^2 - 14^2
PR^2 = 1156 - 196
PR^2 = 960
PR =

3. PQ^2 = QR^2 - PR^2
PQ^2 = 13^2 - 12^2
PQ^2 = 169 - 144
PQ^2 = 25
PQ = 5

maaf yg no 2 gatau & maaf kalo salah._.
