similar polygons have sides in the same proportion if jkl ~qrs that means jk corresponds to qr and kl corresponds to rs and lj corresponds to sq

OpenStudy (quickthing):

right

OpenStudy (quickthing):

i tried setting the corresponding parts equal to each other

OpenStudy (quickthing):

didn't work

OpenStudy (alyssa_xo):

show me your proprtion

OpenStudy (quickthing):

e.g. x+4=24, 2x-1=36

OpenStudy (alyssa_xo):

that's not the equality the sides are in proportion with each other

OpenStudy (quickthing):

Oh.

OpenStudy (alyssa_xo):

I'll set it up

OpenStudy (quickthing):

Thanks

OpenStudy (quickthing):

That would help

OpenStudy (alyssa_xo):

so \(\large \dfrac{JK}{QR}=\dfrac{JL}{QS}\implies \dfrac{24}{x+4}=\dfrac{36}{2x-1}\)

OpenStudy (quickthing):

Thanks. That's what I did, but I didn't know how to solve it.

OpenStudy (alyssa_xo):

that's not what you did if what you wrote was " x+4=24, 2x-1=36" either way, you can "Cross multiply" and solve for x technically cross multiplying isn't a thing, you're just multiplying and dividing to solve for x

OpenStudy (quickthing):

2x-1*24?

OpenStudy (quickthing):

OK, let me see

OpenStudy (alyssa_xo):

36(x+4)=24(2x-1)
