Question

Δ ABC is right angled at C. If AB = 13 cm and AC = 5 cm.Find the length of BC.​

Answer 1

Answer:

12 cm

Step-by-step explanation:

Given: ABC is a right triangle in which, AB = 13 cm & AC = 5 cm

Solution:

We know that in a right-angled triangle,

h² = b² + p²

A/Q, h = 13 cm & p = 5 cm

h² = b² + p²

=> 13² = b² + 5²

=> b² = 169 - 25

=> b² = 144

=> b = root 144

b = 12 cm

Therefore, the length of BC = b = 12 cm.
