## anonymous 4 years ago 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... $distance = \sqrt{a ^{2} + b ^{2}}$

i dont know how to solve this

ohh ok

wait wat are we finding? c^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.

@whadduptori Hi, I need help with this question too! Would the answer be 7?
