I'm sorry but did they mention any other angle's degree??

- anonymous

no they didnt

no one likes this kind of geometry do they?

- anonymous

no lol

- anonymous

i dont get it

- anonymous

i am sure it is doable though lets see what we can come up with

- anonymous

okay thanks

- anonymous

let me try to draw it

- anonymous

okay

- anonymous

damn screwed up already, go the sides wrong
gotta start over

- anonymous

|dw:1442803070373:dw|

- anonymous

alrighty

- anonymous

|dw:1442803248679:dw|

- anonymous

okay.. how do i figure out the measurements?

- anonymous

now lets fill in the 72 we didn't do that yet

- anonymous

|dw:1442803341238:dw|

- anonymous

now we can find angles RSQ and RQS because the are equal in the internal angles of a triangle add up to 180
we have used up 72 already, that leaves \(180-72=108\)
halve of that is \(54\) so each of those must be 54

- anonymous

|dw:1442803491836:dw|

- anonymous

seem reasonable?

- anonymous

yes it does but do we put 54 as the answer or what do we put

- anonymous

54 is the answer to the first two questions

- anonymous

oh okay

- anonymous

now lets fill in another
since a line also has 180 degrees we can find \(180-54=126\)

- anonymous

|dw:1442803708556:dw|

- anonymous

okay

- anonymous

that is angle SQP number 4 in your questions

- anonymous

the third and 5th are like before
subtract \(126\) from \(180\) then divide by 2

- anonymous

27?

- anonymous

can you help me with another part? @satellite73

- anonymous

yeah 27

- anonymous

you mean there is more? taxing my brain already, but i can look

ok they are all equal and they all add up to 180 i guess we can solve that with some algebra (i hope)

- anonymous

\[3a+4+6b+19c+3=180\] and \[3a+4=6b=19c+3\]

- anonymous

this is going to suck a bit
how is your algebra?

- anonymous

oh my favorite algebra (sarcasm)

- anonymous

okay

- anonymous

we can also write each of the bottom equations in terms of one variable
maybe \(b\)

- anonymous

okay okay i kinda get it

- anonymous

so far so good? we have \(a\) in terms of \(b\)

- anonymous

actually i am being a little stupid here, lets work smarter

- anonymous

oh

- anonymous

clear or no? just subtracted is all

- anonymous

i got it

- anonymous

ok
now we can solve
but before we do that, let me say that i am really stupid tonight

- anonymous

all the sides are the same, so all the angles are the same
since they add up to 180, they are all 60

- anonymous

no youre fine

- anonymous

if \(6b=60\) then \(b=10\)

- anonymous

so a b c are 60?

- anonymous

no \(6b=60\) so \(b=10\)

- anonymous

oh okay

- anonymous

and also \[3a+4=60\] so \[3a=56\] making \[a=\frac{54}{3}\]

- anonymous

A - 18?

- anonymous

and finally \[19c+3=60\] so \[19c=57\] making \[c=\frac{57}{19}\]

- anonymous

A=18 sorry

- anonymous

typo there \[3a+4=60\\
3a=56\\
a=\frac{56}{3}\] it is not a whole number

- anonymous

so a and c arent whole numbers and thats okay

- anonymous

actually c is a whole number

- anonymous

\[57\div 19=3\]

- anonymous

oh okay

- anonymous

only a is not a whole number
this was not nearly as hard as it looks, just had to solve 3 equations \[3a+4=60\\
6b=60\\
19c+3=60\]

- anonymous

is there more or are we done?

- anonymous

that was it thank you so much !!

- anonymous

yw
now i have a question

- anonymous

why are you legendary?

- anonymous

is that a serious question? lol

- anonymous

sorta
just a nick name or did you make it up?

- anonymous

nick name

- anonymous

cool lol
