Final answer:

After setting BD equal to AD and DC, and solving the equations, we find that x = 10 and y = 2.

Consequently, BD, AD, and DC measure 13 units each, and the hypotenuse AC measures 26 units.

Step-by-step explanation:

We are given a right triangle ABC with BD as the median to the hypotenuse AC.

The lengths of segments are given as BD = x + 3, AD = 6y + 1, and DC = x + y + 1.

By the properties of a median to the hypotenuse in a right triangle, we know that BD = AD = DC.

Thus, setting BD equal to AD and BD equal to DC provides us with two equations:

  • x + 3 = 6y + 1
  • x + 3 = x + y + 1

Solving the first equation for y gives us y = (x + 2)/6.

Solving the second equation for y gives us y = 2.

Substituting y = 2 into the first equation, we get x = 6(2) - 2 = 10.

Now, calculating the lengths:

BD = x + 3

= 10 + 3

= 13

AD = 6y + 1

= 6(2) + 1

= 13

DC = x + y + 1

= 10 + 2 + 1

= 13

Since BD is the median to the hypotenuse, AC is twice the length of BD:

AC = 2 * BD

= 2 * 13

= 26
