Hey there!
Yes this triangle is a right triangle. Leg lengths 4 and 5 in. would be the legs and the 7 inch would be the hypotenuse.
Hope this helped!

Explanation:
______________________________________________
Let us represent the TWO (2) numbers with the variables; 
         "x" and "y" .
__________________________________________
     x + y = 47 .
     y − x = 25.
__________________________________________
Since:  " y − x = 25 " ;
Solve for "y" in terms of "x" ;
  y − x = 25  ;
Add "x" to each side of the equation:
_____________________________________________
   y − x + x  = 25 + x  ;
to get:
   y = 25 + x .
Now, since:
  x + y = 47 ; 
Plug in "(25 + x)" as a substitution for "y"; to solve for "x" :
x + (25 + x) = 47  ;
x + 25 + x + 47 ;
2x + 25 = 47 ;
Subtract "25" from each side of the equation:
2x + 25 − 25 = 47 − 25 ;
2x  = 22  ;
Divide EACH SIDE of the equation by "2" ; 
 to isolate "x" on one side of the equation; and to solve for "x" ; 
  
2x / 2 = 22 / 2 ;
    x = 11 ;
______________________________________________
x + y = 47<span> ;
</span>Plug in "11" for "x" into the equation ; to solve for "y" ;
11 + y = 47 ;
Subtract "11" from EACH SIDE of the equation;
  to isolate "y" on one side of the equation; and to solve for "y" ;
 11 + y − 11 =  47 − 11  ;
            y = 36 .
___________________________________________
So:  x = 11 , y = 36 ;
___________________________________________
 Let us check our work:
y − x = 25 ; 
36 − 11 =? 25 ?  Yes!
x + y = 47 ; 
36 + 11 =? 47 ? Yes!
______________________________________________
The numbers are:  36 and 11 .
