Angles on a line add to 180. so we could denote angle AEC as x and make everything equal to 180

I know that this angel is supplementary. (= 180 degrees). I just don't remember how to solve this equation to figure out the exact amount that angle AEC =. Do you know how to solve it @marigirl ?

Would you have answers to check my working? I would add all the angles uo AEB+BEC+CED 11x-12+x+4x+1=180 16x-11=189 x=191/16 Calculate angle AEC 11x-12+x =524/4

Which part do I need to solve?
marigirl
  • marigirl
I added all the angles up and made it equal to 180 and then found angle AEC (which is what the question asked) would you be able to look at the answers to see if we are on the right track?

What's the answer?
marigirl
  • marigirl
I think its 525/4 or 131.25 degrees
anonymous
  • anonymous
So AEC = 131.25?
marigirl
  • marigirl
I think so

Are you sure on that answer?

@TQKMB what happened
madhu.mukherjee.946
  • madhu.mukherjee.946
your angle aec =139

  • anonymous
@madhu.mukherjee.946 How did you get 139?

okay wait i'm telling u

@madhu.mukherjee.946 How did you get 139?
madhu.mukherjee.946
  • madhu.mukherjee.946
your ec is bisecting the angle bed
madhu.mukherjee.946
  • madhu.mukherjee.946
so angle ceb =angle ced
madhu.mukherjee.946
  • madhu.mukherjee.946
so if angle ced=4x+1 your angle ceb =4x+1
madhu.mukherjee.946
  • madhu.mukherjee.946
now angle aeb=11x-12 is given
madhu.mukherjee.946
  • madhu.mukherjee.946
now there is a geometric property that states that angles on a straight line =180
madhu.mukherjee.946
  • madhu.mukherjee.946
now 4x+1+4x+1+11x-12=180 19x-10=180 19x=190 x=10
madhu.mukherjee.946
  • madhu.mukherjee.946
so now angle aec=angle aeb+angle bec =11x-12+4x+1 now putting x=10 =110-12+40+1 =139
