Me determine which relation is a function.

In a certain pentagon, the interior angles are a, b,c, d,e where a, b,c, d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

Me with these questions , i don’t understand scientific notation!

Circle a is intersected by lm and mo 60° 155 what is the measure of lmo enter your answer as a decimal in the box. mlmo =
