I need some geometry help. Is JKF acute, obtuse or right? I did a bit of work on it already and now I am stuck. It could be wrong though.
Thank you!!

Sherina wrote and solved the equation. x-56=230 x-56-56=230-56 x=174 what was sherina’s error? sherina’s work is correct. sherina only needed to subtract 56 from 230. sherina made a subtraction error when subtracting 56 from 230. sherina should have added 56 to both sides of the equation.
