Answer:
56
Step-by-step explanation:
Since the two triangles are similar, they have proportional sides. For instance, a proportion that can be made with the hypotenuse is [tex]\frac{106}{53}[/tex], which simplifies to 2. This means that triangle DEF's sides are half the size of triangle ABC's sides. Therefore, if you multiply 28 by 2, you get 56.
