yeah sure tag the poor lgba :(
It would be 180 - 60
120..but can you explain to me why? becuase I want to learn for next time!
if you have 4 parallel lines like this |dw:1339087707750:dw|
all the intersections are exactly the same
so those angles are exactly the same
so that angle is 60
and they told us its against a line
so from there to there is 180
all thats left is the difference
oh ok I see! terrific..there was another way I looked at it too! if you look at the picture angle K has one arc which measures 60 degrees, and angle M has two arcs! so I was thinking that I could multiply 60 times 2!
will that technique work on all equations?
the arc simply mean that they are different angles
they dont have to be different by a factor of 2 tho
oh ok I see! thanx ;)
