@TheSmartOne Helppp

OpenStudy (anonymous):

someone please help D:

OpenStudy (anonymous):

OpenStudy (anonymous):

I have this bad feeling that you have no idea how to do this and I'm gonna spend a half hour explaining this. I hope not.

OpenStudy (anonymous):

._.

OpenStudy (anonymous):

Well all you gotta do is prove me wrong, eh?

OpenStudy (anonymous):

I don't know how...

OpenStudy (anonymous):

Anyways, let's get onto it.

OpenStudy (anonymous):

yay

OpenStudy (anonymous):

The first tip, that RS is congruent to ST is pretty important. because that means that the angles SRT and STR are also congruent.

OpenStudy (anonymous):

right right

OpenStudy (anonymous):

So let's say they are both theta. That sound good?

OpenStudy (anonymous):

We know that the angle of STU and STR will add together to be 180, right?

OpenStudy (anonymous):

right :o

OpenStudy (anonymous):

We also know that the 3 angles of a triangle will add to be 180, right?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

So we can construct a system of equations with x and theta based on those two pieces of knowledge.

OpenStudy (anonymous):

:o

OpenStudy (anonymous):

I just noticed, but there is a (1 point) thing on your attachment, this isn't for a quiz, is it?

OpenStudy (anonymous):

It's for a practice thing

OpenStudy (anonymous):

and I also don't know how to do this >_<

OpenStudy (anonymous):

my brain is like rambling

OpenStudy (anonymous):

You are writing this stuff down right? Don't try to do it all in your head, much easier to write (and draw) it down.

OpenStudy (anonymous):

I am :(((

OpenStudy (anonymous):

I still don't know how to find the answer D:

OpenStudy (anonymous):

Do you know how to make and solve a system of equations?

OpenStudy (anonymous):

umm...no ._. Well not this atleast

OpenStudy (anonymous):

Hmmmm

OpenStudy (anonymous):

D:

OpenStudy (anonymous):

Idk what to tell you. There is some level of knowledge required to ask certain questions.

OpenStudy (anonymous):

Like how do I solve this? I honestly don't know and I've been stuck on this since last weekend D:

OpenStudy (anonymous):

this question been driving me crazy

OpenStudy (anonymous):

You can comprise two equations that both contain x and theta, and then use a system of equations to solve for x. That's how I did it, and it took me about 5 minutes.

OpenStudy (anonymous):

and what did you get? :o could you like do the steps for me?

OpenStudy (anonymous):

You know what, fine. I'll take a picture of it.

OpenStudy (anonymous):

yayy

OpenStudy (anonymous):

OpenStudy (anonymous):

what does the last part say :o

OpenStudy (anonymous):

Well I was solving the system of equations for x.

OpenStudy (anonymous):

You know what? Just have someone help you solve this system of equations for x \[\large \sf 8x+\theta = 180\\\large \sf 7x+2\theta = 234\]

OpenStudy (anonymous):

okay :(

OpenStudy (anonymous):

THank you <3

OpenStudy (anonymous):

No problem, good luck

OpenStudy (anonymous):

*sigh*

OpenStudy (anonymous):
