Question

In right angled triangle ABC, AB = 12cm, BC = 9cm, AC = ?

Hypotenuse = ?

​

Answer 1

Answer:

Hypotenuse = 15cm

Step-by-step explanation:

In right angled ΔABC, m∠ABC = 90°

According to Pythagoras theorem,

AC² = AB² + BC²

=> AC² = 12² + 9²

=> AC² = 144 + 81

=> AC² = 225

=> AC = √225

=> AC = 15cm.

Hence, The length of hypotenuse is 15cm.
