nevaehhh:

Can anyone explain this to me? I'm pretty confused.

SaltTheLoser:

Math aint my strong suit so im gonna go

nevaehhh:

Oddmoyu123:

if not one sec

jhonyy9:

no direct answers never

jhonyy9:

how you ve get this result ?

nevaehhh:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 no direct answers never \(\color{#0cbb34}{\text{End of Quote}}\) I wasn't looking for x, so it isn't a direct answer.

Oddmoyu123:

i gace her the value of x that is only the first step in finding the radius

jhonyy9:

this not is the radius

nevaehhh:

Can someone just help me?

jhonyy9:

moment pls

Oddmoyu123:

maybe jhonyy look at the question i think you can figure it faster

Oddmoyu123:

than i

SemiDefinite:

recognise that QA = QB from pure symmetry does that help?

nevaehhh:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @SemiDefinite recognise that QA = QB from pure symmetry does that help? \(\color{#0cbb34}{\text{End of Quote}}\) QA and QB being what ?

Oddmoyu123:

but qa dose not equal r

Oddmoyu123:

4x+3= 7x-6

Oddmoyu123:

x =3 as i said earlier

SemiDefinite:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @nevaehhh \(\color{#0cbb34}{\text{Originally Posted by}}\) @SemiDefinite recognise that QA = QB from pure symmetry does that help? \(\color{#0cbb34}{\text{End of Quote}}\) QA and QB being what ? \(\color{#0cbb34}{\text{End of Quote}}\) the length QA & QB on the diagram i am deliberately avoiding geometry terms.

Oddmoyu123:

the rest of this step is arithmetic

nevaehhh:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @SemiDefinite \(\color{#0cbb34}{\text{Originally Posted by}}\) @nevaehhh \(\color{#0cbb34}{\text{Originally Posted by}}\) @SemiDefinite recognise that QA = QB from pure symmetry does that help? \(\color{#0cbb34}{\text{End of Quote}}\) QA and QB being what ? \(\color{#0cbb34}{\text{End of Quote}}\) the length QA & QB on the diagram i am deliberately avoiding geometry terms. \(\color{#0cbb34}{\text{End of Quote}}\) Oh I'm sorry, I didn't notice that the center was labeled Q .

Oddmoyu123:

lmao

jhonyy9:

|dw:1608164205781:dw| any idea now ?

nevaehhh:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 Created with RaphaëlrrrrEFQHG4x +37x -6Reply Using Drawing any idea now ? \(\color{#0cbb34}{\text{End of Quote}}\) The diagram helped a little, but my teacher hasn't explained this at all, mind you.

Oddmoyu123:

nice job jhonyy

jhonyy9:

ohh sorry i ve forget HG and EF = 16

jhonyy9:

yeah - ty

nevaehhh:

Do we solve the triangles to find the radius ?

jhonyy9:

exactly

jhonyy9:

how you think these triangles QEF and QHG what style of triangles are ?

jhonyy9:

with two equal sides

nevaehhh:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 how you think these triangles QEF and QHG what style of triangles are ? \(\color{#0cbb34}{\text{End of Quote}}\) an isosceles ?

jhonyy9:

exactly

Hero:

No giving of any answers allowed. If your start to helping a user begins with "x=a", you're giving the answer. Explain, demonstrate, conceptualize.

nevaehhh:

Could you possibly explain how to find the two sides of the isosceles triangle ?

Oddmoyu123:

side a = side b

nevaehhh:

Well ig no one is going to explain how to solve the triangle lmao

jhonyy9:

ok moment pls

jhonyy9:

|dw:1608164994582:dw|

nevaehhh:

x=3, which is the height of the triangle

SemiDefinite:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @nevaehhh \(\color{#0cbb34}{\text{Originally Posted by}}\) @SemiDefinite \(\color{#0cbb34}{\text{Originally Posted by}}\) @nevaehhh \(\color{#0cbb34}{\text{Originally Posted by}}\) @SemiDefinite recognise that QA = QB from pure symmetry does that help? \(\color{#0cbb34}{\text{End of Quote}}\) QA and QB being what ? \(\color{#0cbb34}{\text{End of Quote}}\) the length QA & QB on the diagram i am deliberately avoiding geometry terms. \(\color{#0cbb34}{\text{End of Quote}}\) Oh I'm sorry, I didn't notice that the center was labeled Q . \(\color{#0cbb34}{\text{End of Quote}}\) QA = QB allows you to solve for x Then: AE = AF = BH = BG = 8 that allows you to solve for QF or QG, simply using Pythagoreas, eg: - \(QA^2 + AF^2 = QF^2 \qquad [= r^2]\) - \(QB^2 + BG^2 = QG^2 \qquad [= r^2]\) etc

jhonyy9:

yes so than you know the height and you know that the base is halfed so 16/2 and from this triangle you can calcule the r

nevaehhh:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 yes so than you know the height and you know that the base is halfed so 16/2 and from this triangle you can calcule the r \(\color{#0cbb34}{\text{End of Quote}}\) I'm sorry, but I'm confused as to how we can find the radius of the circle from the triangle.

jhonyy9:

ok you know the height yes that is 3 and the base halved is 8 so r^2 = 3^2 +8^2

nevaehhh:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 ok you know the height yes that is 3 and the base halved is 8 so r^2 = 3^2 +8^2 \(\color{#0cbb34}{\text{End of Quote}}\) I already solved the triangle, i got 16 as the base, and 8.54 as the two sides.

jhonyy9:

sorry x = 3 so the height is 4*3+3 = 15

nevaehhh:

Ok, Imma redo the the triangle right quick.

nevaehhh:

I got 16 as the base, and 17 as the two sides of the triangle, for the top triangle.

jhonyy9:

r^2 = 15^2 +8^2

jhonyy9:

r = ?

jhonyy9:

r = 17

nevaehhh:

The radius of the circle is 17 ? I don't understand how the radius is 17, when the line doesn't completely touch half through the circle.

jhonyy9:

look please on my posted image

nevaehhh:

Thank you for helping me.

jhonyy9:

do you understand it now to all ?

nevaehhh:

Yes, I understand it now, thank you again.

jhonyy9:

anytime bye bye
