the problem looks like this

given that measurment arc LM=84
and measurmen arc KN=116
fixed it, thanks

I know you fixed it but I had to have a go at it anyway. It was a matter of honour...
I was trying to be a smart Alec working out all the permutations of opposite angles and whatever and I nearly missed the fact that the centre point of the circle was on JL. This meant that JL was the diameter.
If I remember my basic geometry; any triangle in a circle who's hypotenuse is on the diameter and common angle is on the circumference has to be 90 degrees.
Nice one.
