Answer 2

In right triangle ABC, angle C is a right angle, AB = 13, and BC = 5, then the length of AC = 12.

Given:

In right-angled triangle ABC, angle C is a right angle.

AB=13, and BC=5

To find:

The length of AC

Solution:

Since in right-angled triangle ABC, angle C is a right angle, it implies that in this triangle, AB is the hypotenuse, and BC and AC forms the other 2 sides.

Using the Pythagoras theorem, we can say

AB² = BC² + AC²

Substituting the values of AB and BC, we get

13² = 5² + AC²

=> AC² = 13² - 5²

=> AC² = 169 - 25

=> AC² = 144

=> AC = √144

=> AC = 12

Hence,

the length of AC = 12
