Robin hikes due south for 6 km. Then she hikes due east for 3.25 km. What is the best estimate, in km, of the distance from her starting point?

    you can use Pythagorean theorem... \[a ^{2} + b ^{2} = c ^{2}\] so... \[distance = \sqrt{a ^{2} + b ^{2}}\]

    the distance on that diagonal would be "c" And the relationship is that c^2 = a^2 + b^2 but you need to solve for c, not c^2.
