@MysticalFlames

OpenStudy (anonymous):

hey i gotta go for like 20 mins but I'll give you all your answers when I'm back just post them

OpenStudy (shadowlegendx):

Do they provide additional information @Mimi_Styles ?

OpenStudy (anonymous):

@MysticalFlames okay

OpenStudy (anonymous):

@ShadowLegendX and no they don't

OpenStudy (shadowlegendx):

Do they have multiple choice answers available?

OpenStudy (anonymous):

no. :/

OpenStudy (shadowlegendx):

I really would like to assume <BDA and <CDA are 90 degree angles

OpenStudy (shadowlegendx):

Do you think there is enough information to make such a conclusion

OpenStudy (shadowlegendx):

If so, then this is a piece of cake

OpenStudy (anonymous):

umm I don't know :o

OpenStudy (anonymous):

D: are you still here?

OpenStudy (shadowlegendx):

Well we know BA and CA are congruent As well as <BAD and <CAD being congruent Also, they share a side, right in the middle(forget what thatʻs called), but that means they both share line AD, so they are congruent there as well

OpenStudy (anonymous):

ohh :o

OpenStudy (anonymous):

but how do I find the answer

OpenStudy (shadowlegendx):

Thatʻs the thing, I remember some stuff from Geometry, but I havenʻt done it in a while. And I lost my Geometry notebook as well, so I canʻt refer back to it.

OpenStudy (anonymous):

Got it

OpenStudy (anonymous):

x is a 90 degree angle

OpenStudy (shadowlegendx):

@MysticalFlames You remember this?

OpenStudy (shadowlegendx):

Thought so

OpenStudy (anonymous):

yup

OpenStudy (shadowlegendx):

Now just have everything add up to 180 and itʻs cake. @MysticalFlames I thought it would be 90 degrees, but I was unsure. When Iʻm unsure, I donʻt teach a user it as it could be incorrect, thus them learning something wrong. Ty for the assistance.

OpenStudy (anonymous):

>_> <_<

OpenStudy (shadowlegendx):

180 = 90 + 47 + y

OpenStudy (shadowlegendx):

Solve

OpenStudy (shadowlegendx):

That will give you y

OpenStudy (anonymous):

so since triangles add up to 180 degrees 90+47+y=180

OpenStudy (anonymous):

43

OpenStudy (shadowlegendx):

with us already knowing x = 90. Since line AD and BC are perpendicular, we know that the angle adjacent to x is 90 degrees as well
