I'm sorry but did they mention any other angle's degree??
anonymous
  • anonymous
no they didnt

no one likes this kind of geometry do they?
anonymous
  • anonymous
no lol
anonymous
  • anonymous
i dont get it
anonymous
  • anonymous
i am sure it is doable though lets see what we can come up with
anonymous
  • anonymous
okay thanks
anonymous
  • anonymous
let me try to draw it
anonymous
  • anonymous
okay
anonymous
  • anonymous
damn screwed up already, go the sides wrong gotta start over

anonymous
  • anonymous
alrighty
anonymous
  • anonymous
|dw:1442803248679:dw|
anonymous
  • anonymous
okay.. how do i figure out the measurements?
anonymous
  • anonymous
now lets fill in the 72 we didn't do that yet
anonymous
  • anonymous
|dw:1442803341238:dw|
anonymous
  • 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
  • anonymous
|dw:1442803491836:dw|
anonymous
  • anonymous
seem reasonable?
anonymous
  • anonymous
yes it does but do we put 54 as the answer or what do we put
anonymous
  • anonymous
54 is the answer to the first two questions
anonymous
  • anonymous
oh okay
anonymous
  • anonymous
now lets fill in another since a line also has 180 degrees we can find \(180-54=126\)
anonymous
  • anonymous
|dw:1442803708556:dw|
anonymous
  • anonymous
okay
anonymous
  • anonymous
that is angle SQP number 4 in your questions
anonymous
  • anonymous
the third and 5th are like before subtract \(126\) from \(180\) then divide by 2
anonymous
  • anonymous
27?
anonymous
  • anonymous
can you help me with another part? @satellite73
anonymous
  • anonymous
yeah 27
anonymous
  • 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
  • anonymous
\[3a+4+6b+19c+3=180\] and \[3a+4=6b=19c+3\]
anonymous
  • anonymous
this is going to suck a bit how is your algebra?
anonymous
  • anonymous
oh my favorite algebra (sarcasm)
anonymous
  • anonymous
okay
anonymous
  • anonymous
we can also write each of the bottom equations in terms of one variable maybe \(b\)
anonymous
  • anonymous
okay okay i kinda get it
anonymous
  • anonymous
so far so good? we have \(a\) in terms of \(b\)
anonymous
  • anonymous
actually i am being a little stupid here, lets work smarter
anonymous
  • anonymous
oh
anonymous
  • anonymous
clear or no? just subtracted is all
anonymous
  • anonymous
i got it
anonymous
  • anonymous
ok now we can solve but before we do that, let me say that i am really stupid tonight
anonymous
  • 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
  • anonymous
no youre fine
anonymous
  • anonymous
if \(6b=60\) then \(b=10\)
anonymous
  • anonymous
so a b c are 60?
anonymous
  • anonymous
no \(6b=60\) so \(b=10\)
anonymous
  • anonymous
oh okay
anonymous
  • anonymous
and also \[3a+4=60\] so \[3a=56\] making \[a=\frac{54}{3}\]
anonymous
  • anonymous
A - 18?
anonymous
  • anonymous
and finally \[19c+3=60\] so \[19c=57\] making \[c=\frac{57}{19}\]
anonymous
  • anonymous
A=18 sorry
anonymous
  • anonymous
typo there \[3a+4=60\\ 3a=56\\ a=\frac{56}{3}\] it is not a whole number
anonymous
  • anonymous
so a and c arent whole numbers and thats okay
anonymous
  • anonymous
actually c is a whole number
anonymous
  • anonymous
\[57\div 19=3\]
anonymous
  • anonymous
oh okay
anonymous
  • 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
  • anonymous
is there more or are we done?
anonymous
  • anonymous
that was it thank you so much !!
anonymous
  • anonymous
yw now i have a question
anonymous
  • anonymous
why are you legendary?
anonymous
  • anonymous
is that a serious question? lol
anonymous
  • anonymous
sorta just a nick name or did you make it up?
anonymous
  • anonymous
nick name
anonymous
  • anonymous
cool lol
