In the figure below, what is the length of
MN?

C, 17

Step-by-step explanation:

For questions like this, we need to use the Pythagorean theorem, a^2+b^2=c^2

in this case, a and b are MP and PN, respectively.

So, we would get

8^2+15^2=MN^2

Simplify to get 64+225=MN^2,

289=MN^2

MN=√289

MN=17

rounding to the nearest thousandth would be 452,000
