What is the length of bc in the right triangle below
a. square root 270
b.21
c.39
d.51
e.270
f.1521

To solve for this, we need to use Pythagorean Theorum.
Pythagorean Theorum is when we add the squares of the legs (A & B) to solve for the hypotenuse (C) or the side that's across from the 90 degree angle.
The formula for Pythagorean Theorum is A^2 + B^2 = C^2.

We have our two leg lengths, 15 and 36 (A & B).
Square 15 and 36.
15^2 = 225
36^2 = 1,296

Now that we have our side lengths, let's add them up.
225 + 1,296 = 1,521.

Now, to solve for C, we need to square root our sum.

The square root of 1,521 is 39.

Your hypotenuse is 39.

Your answer is C.) 39.

I hope this helps!
