Robert left his house and biked 12km east before changing direction. He then biked 16 km south. If he bikes home on the most direct path to his house, how many kilometers must he travel?
|dw:1339479231206:dw| use Pythagorean theorem to solve out for x
and that would be your answer :)
is there another way to solve it ? like an equation or something?
yes the pythagorean theorem there probably is another way to solve this but using the theorem is the easiest way
\[c^{2} = a^{2} + b^{2}\] \[c^{2} = 12^{2} + 16^{2}\] \[c^{2} = 144 + 256\] Can you solve it now?
