Answer:
17 blocks
Explanation:
Because this will create a right triangle, you can find this using the Pythagorean Theorem.
A quick refresher (Or a lesson if you haven't learned this yet), the equation for the Pythagorean Theorem is a^2+b^2=c^2. A and B are the sides that make up the right angle and can be used interchangeably. C is the other side and the one we are going to find.
Let's first plug-in the numbers we already know.
a^2+b^2=c^2 -> 15^2+8^2=c^2
We'll then calculate 15^2 and 8^2
You'll find that this equals 225 and 64.
You now have 225+64=c^2
Add 225 and 64,
289=c^2
The final step is to simplify c^2 into c. You will have to square c^2 and because of that must also square 289

17=c
c=17
