phi

any idea what the angle
anonymous

That's where I get confused, because there is no actual number for x.
phi
  • phi
it does not matter what the number is ... the idea is those two angles form a straight line and a straight line is an angle of how many degrees?

Oh, I got x=26. I subtracted 154 from 180
phi
  • phi
yes. we also know the two "marked angles" are equal (that is what the red arcs mean) if we call them Y (for convenience) the 3 angles of the triangle Y+Y+X= 180 and also from the first post 154+X= 180 so we can say 2Y+ X = 154+X or (subtract off X from both sides) 2Y= 154 now you can find Y (i.e. angle HIJ)

I got y=77 degrees, thank you for all the help!!
phi
  • phi
or we could use x=26 and say 2Y+26= 180 2Y= 180-26 2Y= 154 Y= 77
phi
  • phi
the reasoning was a bit complicated... once people figured it out they said let the < GHJ be called an "exterior angle" and the exterior angle equals the sum of the two opposite angles. that lets you write down

I posted a similar one just now, it's even harder. Your explanation makes sense, thank you again!
