Step-by-step explanation:
Given that,
BC = 8 
Ac = 15 
We can find AB using the pythagoas theorem.

We know that,
 , B is base and H is Hypotenuse
, B is base and H is Hypotenuse

Hence, this is the required solution.
 
        
             
        
        
        
The answer is 60 because were subtracting in the equation but to find m we need to the opposite which is to add 53 plus 7 which is 60. To check your answer do 60-7 equals 53
