Given:
The figure of a right triangle.
To find:
The length of AB.
Solution:
In a right angle triangle,

Using this trigonometric ratio for the given triangle, we get





Therefore, the length of AB is 5 units.
 
        
             
        
        
        
The equation would be -5+(-12), so the answer would be -17 :)
