Marsden:

The diagram below models the layout at a carnival where G, R, P, C, B, and E are various locations on the grounds. GRPC is a parallelogram. Part C: Find the distance from B to E and from P to E. Show your work. Sorry, I just do not understand.

jhonyy9:

i ve solved this problem a few days ago

jhonyy9:

just use the proportionality of corresponding sides

Marsden:

No, sorry, still confused. How can I use that to help? Sorry.

Marsden:

Imagine:

@jhonyy9

Imagine:

I am not smart enough for this.

Marsden:

I am not smart enough for this either.

jhonyy9:

so you need calcule the length of BE and PE so how i ve wrote above use the proportionality of corresponding sides and write in this way GB / BE = CB / BP so what you get with numbers ? can you calcule from this the length of BE ?

jhonyy9:

can you calcule ?

Marsden:

so when you plug it in it would be 425/x=325/225?

jhonyy9:

exactly and from this x = ?

jhonyy9:

ok cross multiplie what you get ?

Marsden:

294.23 is x or is that way off?

jhonyy9:

425*225 = x*325 x = 425 * 225 / 325 = ?

Marsden:

95625 = x*325 3825/13

jhonyy9:

294,23 is correct

jhonyy9:

so this is BE and now PE = ?

jhonyy9:

use how i ve wrote for BE

Marsden:

so CG/PE = CB/BP or CG/PE = gb/be

Marsden:

Sorry, I am really confused.

jhonyy9:

correct - this is right but i say use the given length with integers - will be more easy to make the calcule

Marsden:

256.15

Marsden:

375 times 222 equals 83250 3330/13 is 256.15

Marsden:

Correct?

Marsden:

Or am I way wrong?

jhonyy9:

325 / 225 = 375 / x 325 x = 225 *375 x = 225*375 / 325 = ?

Marsden:

Oh I did 222

jhonyy9:

where ?

Marsden:

259.62 When I calculated i ==I did 325/222 instead of 325/225

Marsden:

Because 375 times 225 is 84375 3375/13 259.62

Marsden:

Right?

jhonyy9:

yes right sure

Marsden:

Thank you and sorry for taking so much of your time.

jhonyy9:

np always is my pleasure to be here and help students - than i can yw bye bye

jhonyy9:

@Marsden do you have questions ?

Marsden:

No

Marsden:

Just new and did not see the close button

jhonyy9:

ok bye bye hnd
