Answer 1

AC² =AB²+BC ²

so 5²=AB² + 12²

144-25=AC²

119= AC²____

AC= / 119

that is root 119

Answer 2

Answer:

13 cm

Step-by-step explanation:

Given,

Base = AC = 5 cm

Perpendicular = BC = 12 cm

Hypotenuse = AB = ?

Let Hypotenuse be x

By phythagoras theorem

(B)²+(P)²=(H)²

(5)²+(12)²=(x)²

25 + 144 = x²

169 = x²

x² = 169

x =√169

x = 13 cm

Hence , length of AB is 13 cm.
