Answer:

ΔABC is right-angled at B.

Therefore, by applying Pythagoras theorem, we obtain AC2 = AB2 + BC2

AC2 = (6 cm)2 + (8 cm)2

AC2 = (36 + 64) cm2 =100 cm2

AC = (√100) cm = (√10x10) cm

AC = 10 cm

(b) ΔABC is right-angled at B.

Therefore, by applying Pythagoras theorem, we obtain AC2 = AB2 + BC2

(13 cm)2 = (AB)2 + (5 cm)2

AB2 = (13 cm)2 − (5 cm)2 = (169 − 25) cm2 = 144 cm2 AB = (√144) cm = (√12x12) cm

AB = 12

maybe u understand.
