Question

In a right triangle ABC,angle B=90° If AC=13cm, BC=5cm, find AB​

Answer 1

Step-by-step explanation:

Let us draw a picture in which B=90°

AC =13cm, BC= 5cm,

So,now By Pythagorams theorem we have,

AC^2 = AB^2 + BC^2

or, AB^2 =Ac^2 - BC^2

= 13^2 - 5^2

= 169 - 25

= 144

So,now AB = √144= 12cm
