The answer is 16

The Pythagorean theorem is a^2+b^2=c^2

You already have one side and the hypotenuse (c)

15^2+b^2=17^2

15^2= 225

17^2= 289

Now you have 225+b^2= 289

Subtract 225 from both sides and you get

b^2=64

Then take the square root of both sides to get b alone

b=8

Now, since the base of the inner triangle is half of the base of the pyramid, multiply your answer by 2

You will get 16
