Question

can someone help with my geometry homework? i wasn't there for the lecture so im so lost. what i have done is based off of background knowledge and some of them are incomplete. so lost and frustrated.

Answer 1

Okay lets start with the first triangle (small one)

Answer 2

We know that the angles inside of a triangle must add up to 180

We have 90 (right angle) and 48 (given)
90+48+\(\angle 1\)=180

Answer 3

<1=42º?

Answer 4

Ya

Answer 5

ok how would we do <2 and <3?

Answer 6

would <2 and <3 be 45º each?

Answer 7

Not quite, the diagram did not say they were equal

Answer 8

oh

Answer 9

Note that there are 2 parallel lines cut by one in between
Angle 2 and 39º are alternate interior angles

Answer 10

Does that make sense?

Answer 11

so <3 woul be 39º because they are alt interior

Answer 12

Right

Answer 13

<2

Answer 14

yes angle 2

Answer 15

that makes sense. would <3 be 51?

Answer 16

Yes

Answer 17

ok are we done with that problem?

Answer 18

Yeah

Answer 19

is #2 right?

Answer 20

Yep

Answer 21

great how do i do #3?

Answer 22

I assume you know how to do angle 2

Answer 23

your images arent working.

Answer 24

Oh

Answer 25

That's weird

Answer 26

Does that work?

Answer 27

yup

Answer 28

would <2 be 29º?

Answer 29

No, its 2 angles on a straight line

They're supplementary lol

Answer 30

would it be 44º?
180-(90+29+17)=44

Answer 31

You're overthinking this
\(\angle 2\)+ 29 =180

Answer 32

oh 151?

Answer 33

Yes

Answer 34

oh

Answer 35

For angles 1 and 3, use the rule that all triangles are adding up to 180
\(\angle 3\)+17+151=180
and
\(\angle 1\)+90+29=180

Answer 36

If you have a question on how I got each number, ask

Answer 37

i understand how you got the numbers.
<3=12
<1=61

Answer 38

Yep

Answer 39

i understand how to do it once its set up for me. but when i look up a new problem im confused about how to set it up

Answer 40

Ah, well most of this is closely paying attention to what is given

For example for the first problem the indication that the lines \(ED\) and \(FC\) were parallel and therefore you needed to use rules

Answer 41

that makes sense

Answer 42

I have to do a bit of homework right now, attempt to do #4 and I'll be back to check on ya

Answer 43

ok, thanks

Answer 44

#4)
<1+<2+105=180
<1+<2=75
28/2 =37.5
75/2=37.5
<1 and <2 = 37.5º

23+24+<3=180
47=180
<3=133º
@dude

Answer 45

Looks right

Answer 46

ok im confused on the back

Answer 47

Can you solve for 1?

Answer 48

Right it doesn't load lol
