Question

Can someone explain this problem, please? Screen cap in the comments.

Answer 1

@SolomonZelman maybe?

Answer 2

Is this on a condition that those triangles are completely congruent??

Answer 3

@JaeJaytheJetplane, I can help you with this, please come back!

Answer 4

I'm sorry, my internet went wacky for a minute!
This is all the information I was given for the problem

Answer 5

Again, Is this on a condition that those triangles are completely congruent??

Answer 6

I said, what you see there is all I know

Answer 7

So apparently they are congruent (or equal)...

you know that their hypotenuses and legs are going to be equal therefore you can say that

3y=x+3
y+5=x

Answer 8

@JaeJaytheJetplane, do you understand why am I saying this?

Answer 9

yes, that's the equation. How do I find the values of the variables?

Answer 10

you can use substitution, matrix, or add them to each other

which methods do you know?

Answer 11

I would substitute
it is given in the second equation that y+5=x
so substitute y+5 for x in the second equation, solve for x

Answer 12

I mean solve for x, after you get the y....

Answer 13

I'm sorry, I still don't understand

Answer 14

OK, can you plug in y+5 for x, into the first equation,

when you do that write the first equation out.

Answer 15

OH! I see now!

Answer 16

so...
y = 4 and x = 9

Answer 17

Yes, right!

RIGHT!!!

But one more thing, without that we would have to rvw this...

@JaeJaytheJetplane, do you understand where I got the

3y=x+3
y+5=x

from?

Answer 18

yeah, those are the corresponding sides

Answer 19

Yep, That's why i kept asking if those trianlgles Are congruent....

God that you get it, that's the main thing!

Answer 20

Thanks so much! This helps a lot!

Answer 21

Anytime, this is just an implication, knowing that triangles are congruent.


geometry, right?
