Question

can someone check my answers?

Answer 1

Sorry I don't think that's correct.



Look at this part and see if you can figure out what the question mark '?' is.

Answer 2

40

Answer 3

right?

Answer 4

Sorry I was gone. Yeah it's 40.

Answer 5

So the measure of angle 3 is 40.
And it says the measure of angle 2 is 45 soooo

Answer 6

Now find the measure of angle 1 here.

Answer 7

95

Answer 8

Yep.

Answer 9

is this correct?

Answer 10

19 + 60 = 150 + 30 = 180

Answer 11

Uh, that angle looks like it's outside of the tent.

Answer 12

I think it's more like this.

Can you find out what '?' is here

Answer 13

120?

Answer 14

Nope. Let me make this easier:



Since it's a straight line, it'll add up to 180.

Answer 15

ah, so it's 150

Answer 16

yeap

Answer 17

RQS is correct, but NMO doesn't seem right.

Answer 18

so B?

Answer 19

yeah

Answer 20

Well the first blank is wrong.

What they did is combine the equations:

1. m<1 + m<2 + m<3 = 180
2. m<3 = 90
| |
| |
\/
m<1 + m<2 + 90 = 180

They replaced m<3 in the first equation with 90. That's called substitution.

Answer 21

And the second blank is wrong as well.

To get from
\[m<1 + m<2 + 90 = 180\]
to
\[m<1 + m<2 = 90\]

You subtract 90 from both sides. So that would be subtraction.

Answer 22

oh, alright

Answer 23

Er, I can't see the proof in that picture. But I'm going to say that you're wrong again xD.

You're 'given' that it's equiangular, and you should always use the 'given' a the beginning of proofs. So the first blank is equiangular.

The second blank is division since you know that all the angles in a triangle add up to 180.

If you divide 180 by 3, because there's 3 angles, all the angles become 60. So it'll be division.

Answer 24

oh, sorry

Answer 25

The first blank is equiangular. Equiangular just means that every angle is the same. <A = <B = <C

The second blank is talking about how they got from
3m<A = 180
to
m<A = 60

Do you know what 'property of equality' they used to do that?

Answer 26

division?

Answer 27

yep

Answer 28

So it'll be the Division property of equality

Answer 29

Well...it is acute since it's less than 90.

Buuuut the question asks for an angle measure, so it should be a number.

Answer 30

then 60.

Answer 31

then 60.

Answer 32

yeah

Answer 33

Yep. That's correct.

Answer 34

Congruent Supplements Theorem is like this:



It uses angles that add up to 180.

But your question has angles that adds up to 90.

so we use the Congruent Complements Theorem instead

Answer 35

Basically anything that says 'supplements' adds up to 180. A straight line.

Anything that says 'complements' adds up to 90. A right-angle.

Answer 36

alright

Answer 37

So the the conclusion is what you get at the very end.

And when you prove something, the thing at the very is always the thing you're trying to 'prove'.

So it would be 'prove' instead.

Statements only lead to the conclusion.

Answer 38

yep

Answer 39

It says 'Given: <1 and <3 are supplementary'

So that's given. Come on that should've been easy.

Answer 40

i'm r e a l l y not good at math...

Answer 41

ah well. Are there any more?

Answer 42

This one is a little harder probably.

Look what he did at line 4.

45 + m<2 = 90 || Transitive Property of Equality

This is actually Substitution Property of Equality

cuz he replaced "m<1" with 45 in "m<1" + m<2 = 90

That's substitution, so it's an 'incorrect reason to justify his statement.'

Answer 43

Actually there's not a single 'Given' in the proof.

Every proof should start with a the givens.

Answer 44

Bro I'm pretty tired now. I don't think I can help much longer.

Answer 45

oh, alright then.

Answer 46

I'll help with this last one

Answer 47

And yes you are correct
