What is the length of BC in the right triangle below

D. 39

you use the pythagorean theorem which is

if you look at the triangle we can see that we have to find the length of the hypotenuse (BC).

so your equation will look like this:  

1.      (solve for )

2. C= 225+1296      (add)

3.  C= 1521               (find the square root of 1521)

4.

Therefore, 39 is your answer

Hope this helps!

your answer   is c
