what is the difference in classification of <1 and <15? Be specific in your reasoning and use geometry vocabulary.m<1=51.5 m<15=74

Angles 15 is an angle between the the segments NL and EL and L is on the ircle so in this case we know that this is the definition for a inscribed angle
and for angle 1 is part of a rigth triangle so in this case we know that is an angle less than 90º so is an acute angle
