Since BC is the hypotenuse...

α = 12
c = 13

Hence..

13² = 12² + ß²
ß = √(13² - 12²)
= √(169 - 144)
= √25
= 5

Hence, AB = 5

I hope this helps!

Answer:

Step-by-step explanation:

Alright, lets get started.

There is a right triangle given, please refer the diagram I have attached.

Using Pythagorean theorem,

[tex]AC^2+AB^2=BC^2[/tex]

Plugging the value of sides in theorem

[tex]12^2 + AB^2 = 13^2[/tex]

[tex]144+AB^2=169[/tex]

[tex]AB^2 = 169-144[/tex]

[tex]AB^2 = 25[/tex]

Taking square root on both sides

[tex]AB = 5[/tex]  ..................   Answer

Hpe it will help :)
