the graph below shows the speed of a roller coaster during the first 30 seconds. describe the change in speed over time.

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?

Ineeeeed this is due tomorrow and i dont know the answer can you find all the exponents

Need on this geometry question. explain how you did it.
