Question 252566
Step 1 - draw a segment going from northeast to southwest. Call is 10 miles. Create a right triangle with lines going east and then south. Label the east 8 miles. You have created a right triangle with a = a (north / south), b = 8, and 
c = 10. Use Pythagorean theorem to find a.
{{{a^2 + 8^2 + 10^2}}}
{{{a^2 + 64 = 100}}}
{{{a^2 = 36}}}
a = 6 miles north.
