ganeshie8 · Answer

Correct!

anonymous · Answer

if its asking for the magnitude... would i place the formula or get a decimal?

anonymous · Answer

i know it sounds like a silly question. but usually it tell me how to place the answer.. whether or not to round it off.... and this time it asks as if it is suppose to come with the sqrt

ganeshie8 · Answer

it seems the 8^2+15^2 is a perfect square
