## anonymous 4 years ago A camping team started from location G and returned to the same camp walking through camps H, I, and J. What is the total distance the team walked? ( on the rectangle GCJI, side G-J is 8 km and a line going through the rectangle is 17 km)

Draw the diagram. It will be easier for people to visualize. And you'll get a faster answer.

ok hold on

First figure out A

6. anonymous

ok, um 45 degrees

7. jagatuba

$\sin A=\frac{opposite leg}{hypotenuse}$

8. anonymous

so its 35 km/

9. jagatuba

How did you arrive at that answer?

Once you have A. Find IJ using $\tan A=\frac{opposite leg}{adjacent leg}$ OR $\cos A=\frac{adjacent}{hypotenuse}$ Once you have IJ it's 2(IJ)+2(JG) to get your answer.
