This is basic Pythagoras. Remember A squared + B squared = C squared?
reverse it and u get c squared - a squared = b squared.
Apply to ur equation. 14.7 squared - 11.9 squared = 216.09 - 141.61 = 74.48 squared. find the square root, 8.630179604156567, and round it to the nearest 10th. That will equal 8.6
Hope it helps!
