Hello,

This question requires the Pythagorean theorem, ever heard of it? It looks like this:
$$a^2 + b^2 = c^2$$

anonymous · Answer

We apply the theorem by taking the smallest sides and assigning them to the variables $a$ and $b$. When variables $a$ and $b$ are equal to $c$ then the set of line segments are possible to create a right triangle. 

@Bballplayer48 do you follow so far?

Yes

So A @Algorithmic

anonymous · Answer

No $A$ would not work.
$$15^2 + 30^2 \ne 35^2$$

anonymous · Answer

Oh

anonymous · Answer

D would?

anonymous · Answer

No... Are you guessing? It is really simple to solve this problem provided you follow my instructions above...

anonymous · Answer

Oh I understand

anonymous · Answer

B

anonymous · Answer

Bingo!

anonymous · Answer

You add both a and b when you get the exponet
then you find the squareroot

anonymous · Answer

15 to the second power + 36 to the second power = 1521 and then the square root is 39

anonymous · Answer

B's work if anyone else is interested:
$$15^3 + 36^2 = 1521$$
$$39^2 = 1521$$
$$1521 = 1521$$

Hence, B is the correct answer. 

Peace.
