Question

Can you tell me how to find the missing angles in a quadrilateral when its drawn this way..? (see figure)

Answer 1

I already know that..
A= 125 , C= 90 , G= 60 & E= 85
So, what can I do to find BDFH's angles?

Answer 2

Are you there?

Answer 3

@FilthyMcNasty yes, why?

Answer 4

A line is equal to 180 degrees, so all the angles on a line also add up to 180

Answer 5

Lets do Line GE 1st, you see it ?

Answer 6

Yep, alright

Answer 7

Theres 3 angles on line GE, 1 is 30 - 1 is 18 the other is unkown

Answer 8

Yep, :) and..?

Answer 9

hold up, lol

Answer 10

haha okay

Answer 11

yes, but it can be solved

Answer 12

20

Answer 13

Where does 20 go?

Answer 14

i mean, 28. <BCD's missing angle

Answer 15

No. I know angle B i 28. i'm asking did u forget to put a number for angle A or H?

Answer 16

oh okay. A=125 H=45

Answer 17

am i right?

Answer 18

-_-. Do you have the original picture? You dont understand what i am asking you.

Answer 19

Yep, i have. up there. lol sorry

Answer 20

You see how all the triangles have the measures of 2 angles? But triangle AHB has only 1 angle measure? Im asking you if there is an angle measure that you forgot to put up there..

Answer 21

Ah, nope. Only 10 is present,

Answer 22

OK then lets just continue ....

Answer 23

A line is equal to 180 degrees, so all the angles on a line also add up to 180

Answer 24

Lets do Line GE 1st, you see it ?

Answer 25

Yep, got that

Answer 26

What are the measures of the 3 angles on that line ?

Answer 27

30 & 18 & 77?

Answer 28

30 & 18 & the other one is <F .. But its blank & we dont know it. You know how to find it ?

Answer 29

Uhm, 180 - 48. ?

Answer 30

Un huh, which is 32. So now we've found 1 angle of the quadrilateral.

Answer 31

Oh, right! :)

Answer 32

Now let's do line EC, what are the 3 angles on that line?

Answer 33

62 , 77 & D

Answer 34

Ok find D

Answer 35

141.

Answer 36

You made a slight mistake. Try again!

Answer 37

Oh! 41

Answer 38

.__.

Answer 39

Yup! & we found another angle of the quadrilateral!

Answer 40

Now lets do Line AC, what are the 3 angles?

Answer 41

:3 10, B.. how do i find the other? :|

Answer 42

Remember BCD is a triangle & the angles add up to 180.

Answer 43

They give you 2 angles already so find the other

Answer 44

find <B

Answer 45

oh okay.. 142?

Answer 46

How did you get that?

Answer 47

90+62= 152, 180-152= 28.
10+28=48.
B= 180-38.
B= 142?
Is there something wrong?

Answer 48

Ohh, i thought you were saying angle B was 142. lol But you're correct. & we've found another angle of the quadrilateral.

Answer 49

Oh, finally. :D

Answer 50

What does the sum of the angles of a quadrilateral add up to?

Answer 51

360.
So, just add up all found angles and subtract it from 360? :)

Answer 52

Exactly. So what is <H?

Answer 53

145?

Answer 54

Yeah, & thats it. You got all the angles of the quadrilateral. & you can em up to see if they add up to 360 degrees and they do.

Answer 55

So were done, is that all you need help with?

Answer 56

OMG! I finally understood. Thank you so so so much!
I still got 1 problem left but I wont burden you too much. xD

Answer 57

It's alright, lol. I can help

Answer 58

Really? Wait up, I'll tag your name.
