Well, ere going to have to figure out what x is so we know for sure

Answer 5

So how many degree are in a triangle?

Answer 6

180?

Answer 7

Yes and that is when you add up all angles so we are going to add up all 3 angles and set it equal to 180

Answer 8

Ok

Answer 9

So 4x-10+2x+15+x=180 can you add like terms on the left side?

Answer 10

What do you mean?

Answer 11

Add the x's up together and the constants or numbers up can you do that? on the left side

Answer 12

No, I'm not very good at that.

Answer 13

Here I'll help what is 4x+2x+x

Answer 14

6x

Answer 15

close 4x+2x=6x but we're still adding 1x so 6x+1x=?

Answer 16

7x

Answer 17

Yes now we need to add our other numbers -10+15=?

Answer 18

@Melody323

Answer 19

12x

Answer 20

No you were right now these are just numbers so you won't get any x's for this part, -10+15=? You can plug it into your calculator if you have to

Answer 21

5

Answer 22

good so all can turn into 7x+5=180

Answer 23

ok

Answer 24

Is it and equiangular triangle?

Answer 25

We gotta figure it out :) were almost done we need to solve for x

Answer 26

ok

Answer 27

Do you know what you need to do first 7x+5=180

Answer 28

No

Answer 29

Get the 5 over to the other side thing of PEMDAS backwards

Answer 30

Answer 31

So you have addition what is the opposite of addition?

Answer 32

Subtraction

Answer 34

Good so 7x=175

Division

Answer 41

Good so divide by 7 on both side you get?

Answer 42

1

Answer 44

X=25 is that what you got?

Answer 45

25

Answer 46

Yes

Answer 47

Yes now plug that into the two angles

Answer 48

4x-10 so 4(25)-10=?

Answer 49
