Question

Help.

Answer 1

RS = ST, hence

SRT = STR(Equal sides have equal opposite angles)

STU = 8x, hence STR = (180-8x) RST = 7x-54

so SRT = 180 - (180-8x+7x-54)

=> x+54

SRT = STR

180-8x = x+54

126 = 9x.

Hence x = 14.

Answer 2

C

Answer 3

3. ASA 4. CPCT(corresponding parts of congruent triangles.)

Answer 4

@e.mccormick

Answer 5

Remember those marks we did tlast night that meant two things were the same? Well, \(\Large\cong \) mean the same thing.

Answer 6

I was looking up the latex for the symbol. LOL. I don't use that one much.

Answer 7

Lol xD Im really bad with the property things so just warning, my stupidness might annoy you if you help me xD

Answer 8

Now, if you look at statement 1 and what the reaon is, then look at where it is given. Then look at statement 3 whre they say they are congruent and use the \cong symbol in latex or \[\cong\]Ta da! Much faster when I know it. LOL

Answer 9

Lol xD

Answer 10

So would reason 3 be given or?

Answer 11

Exactly!

Answer 12

Now, we also talked about what Redlexive Property means last night. Like x=x or 2=2 or anything where they are absolutlely the same. Do you see anything there that is 100% the same? As in both the left and right triangles have a same piece.

Answer 13

Number 2?

Answer 14

4. I skipped 2 for now. Hehe.

Answer 15

But those have different letter in them, so thay are not exactly the same.

Answer 16

Then no idea

Answer 17

What do they share?

Answer 18

The line SD

Answer 19

So would you say SD=SD?

Answer 20

Idk D:

Answer 21

Well, if the Reflexive Property means two things are 100% and exactly the same, like x=x r 2=2, is that concept also the same as saying SD=SD?

Answer 22

I think so

Answer 23

Well, it is a time to know so! Hehe. Because it is.

Answer 24

Yah.

Answer 25

Now I am going to back up to 2. They gave you that they are perpendicular, right?

Answer 26

Yes

Answer 27

So, the next line is talking about the angles being right angles. If I were to relate that to the previous given statement, what would I say? Recalling the previous statemenrt was that they are perpendicular.

Answer 28

No idea...

Answer 29

Yah, this one is one of those, it is so simple you could miss it ones.

Answer 30

OK, the form of it is the important part. Below they say Reflexive Property. That is the form I cma talking about. So some sort of property.

Statement: They are perpendicular Reason: Given
Statement: Their angles are 90 deg Reason: __________ Property
or A Property of ___________ Lines

Answer 31

I really dont know

Answer 32

Look one line abode the reason, in the previous statement...

Answer 33

You making it obvious makes me not wanna say it xD A Property of Perpendicular Lines?

Answer 34

Yah, it really is that obvious. LOL

Answer 35

-.- lol that was #2 right?

Answer 36

Yep! I know, it was all there, right in front of you. Which sometimes makes it hard to see.

Answer 37

Its a pain sometimes, math seems particularly useless

Answer 38

Math is everywhere. Very useful that way. What do you want to bewcome? Many things use math from art to science.

OK, for #5 it is one of those SSS, SAS, ASA things. What have they given you so far?

Answer 39

Sorry about that, net stopped working and I wanna be a vet, but obviously my math sucks..lol. And crap I already submitted the assignment >.< Oh well haha

Answer 40

Wheee. Openstudy stopped working, nt the net.

And it was the given side, the shared side, and some other stuff there, probably SSA.
