Add up? you mean like 12x+4+x+37+20x+80+13x+1 ??
anonymous
  • anonymous
yes.
anonymous
  • anonymous
equate it to 360. you will get a value of x and then find the angle A which is 12x+4.
anonymous
  • anonymous
46x+122=
anonymous
  • anonymous
??? so im wrong again? u,u
anonymous
  • anonymous
wait, i got 120 as the answer? is this correct?

  • anonymous
if the calculations are correct, then its correct.
anonymous
  • anonymous
im still confused about the calculations..?

find. 12x+4.
ganeshie8
  • ganeshie8
but the question is about finding that A
anonymous
  • anonymous
im lost.
ganeshie8
  • ganeshie8
A = 12x + 4 plugin x = 119/23
anonymous
  • anonymous
12(119/23) +4 ?? like that?
anonymous
  • anonymous
yes. you're correct.
anonymous
  • anonymous
i got 1520/23 ... thats not the right answer. :(

ganeshie8
  • ganeshie8
hw ?
anonymous
  • anonymous
what?
ganeshie8
