Answer: (E) Not necessarily, because this wasn't an experiment
Step-by-step explanation:
As much as the results would suggest that the fast-paced music was responsible for the faster finishing time, this conclusion cannot be authoritatively made because this was not technically an experiment but rather a test to satisfy curiosity.

Answer:
x = 135
Step-by-step explanation:
All the angles of a pentagon added up make 540 degrees.
540 - 60 = 480
480 - 150 = 330
330 - 120 = 210
210 - 75 = 135
x = 135
