Calculate the hypotenus

[Andrejjj17]

I'm sorry for my bad English.
By center of gravity (that's how we call them in my language) I mean the lines that connect the ending point of one side with the middle of the opposing side. (See the image)
the lengths of the center of gravity, drawn from the hypotenuse endpoints, are (t1=7) 7cm and 4cm (t2=4). what is the length of the hypotenuse

What is the hypotenuse in this problem? Hypotenuse is the side opposite to the 90 degree angle in a right triangle, as far as I know. Don't see any right triangles here.

You are so picky!
