Question

My daughter Morgan needs help in Geometry anyone willing to help?

Answer 1

just pose the question , we're here to help , that is the sole purpose

Answer 2

post the ques

Answer 3

Please hold

Answer 4

is it Eoin Morgan ?

Answer 5

post a problem

Answer 6

What?

Answer 7

XYZ and XYW are complementary angles. mXYZ = 3x + 9 and mXYW = 5x + 9. What are mXYZ and mXYW ?

Answer 8

next to XYZ is this little < thing

Answer 9

If the angles are complementary , they sum up to 90 degrees , so , 3x + 9 + 5x + 9 = 90

8x + 18 = 90
8x = 90 - 18

8x = 72
x = 72/8 = 9

put the value of x back in the given equations and u get the respective angles

Answer 10

Hello my name is Morgan! :D Okay can we back up here just a little bit please?? How do i put the x back in the given equation?

Answer 11

3x + 9 = 3*9 + 9 = 27 + 9 = 36

Answer 12

Wait, im all confused... im sorry!! im just a little bit slow.. :( stupid autism.... im rlly sorry,

Answer 13

it's okay , tell me what u didn't understand :D

Answer 14

how you got 3x+9-3*9+8=27+9=36....

Answer 15

substitute x with the value we got , remember x = 9 ? , I just put that back

Answer 16

oh okay i got it now!

Answer 17

:D

Answer 18

okay whats next step?

Answer 19

nothing , those are the angles , do the same for 5x + 9 to get the other angle

Answer 20

5x+9 = 5*9 + 9 = 54 + 9 =63

Answer 21

ummm , 5*9 is 45

Answer 22

oh my bad im sorry i read it wrong!

Answer 23

but , ya , that's the idea

Answer 24

5x+9 = 5*9 + 9 = 45 + 9 = 54

Answer 25

U GOT IT :D :D

Answer 26

okay so the answers is 36 & 54 correct joel?

Answer 27

yep , absolutely

Answer 28

Woohoo! that is soo much easier than the teacher made it! okay there is 2 more could we go over if you dont mind? i just wnat to 1000000% understand this :D

Answer 29

U Betcha

Answer 30

ABC and DEF are supplementary angles. The measure of DEF is twenty degrees less than three times the measure of ABC. What are mABC and mDEF?

Answer 31

Okay , now supplementary means that the angles sum upto 180 degrees

let angle ABC = x

So , angle DEF = 3x - 20 , got it?

Answer 32

yeah

Answer 33

Umm , just a question , r u the daughter who needs help or the mother ?

Answer 34

Anywys , ABC + DEF = 180

So , x + 3x - 20 = 180

Try to solve it now

Answer 35

I said awhile ago hi this is morgan haha, im the daughter!

Answer 36

OKAY , :D , good to know :)

Answer 37

Im sorry for asking so many questions but how do you solve it?? can ya point me in right way how to do it?

Answer 38

Ya , u got the "sum upto 180" part , ryte ?

Now we don't know the angles , but we have a relation between them ,

So , let ABC = x

then , according to the Q , DEF is 20 less than 3 times ABC ; that is

DEF = 3x - 20 , now u have bith the angles , just ADD

Answer 39

do i add 3x + 20 together?

Answer 40

No , ABC + DEf = 180

x + 3x - 20 = 180

4x - 20 = 180
4x = 180 + 20
4x = 200
x = 200/4 = 50

Answer 41

oh okay it makes sense now!

Answer 42

:D ,

Answer 43

Got it , sis ?

Answer 44

Got it!

Answer 45

:)D

Answer 46
