Step-by-step explanation:
- In a right triangle, if ∠B is 45°, then ∠C is too.
-- Since ∠B  and  ∠C  are equal, the sides opposite them
are equal too.  This is an isosceles right triangle.  Its legs
are equal.
-- (The hypotenuse)²  =  (one leg)²  +  (the other leg)²
                                   =       (12-ft)²  +  (12-ft)²
                                   =              (144 x 2)
      The hypotenuse  =  √(144 x 2)  =  12√2 .
