Active Learning Assignment?

Angle of Elevation (or Ascent)-the angle from the horizontal, upwards. Review Definition of: Angle of Elevation (or Ascent)-the angle from the horizontal, upwards. Angle of Depression (or Descent)-the angle from the horizontal, downwards Angle of Depression What is the relationship between the two? Why? Angle of Elevation

Instructions: (Assignment is on the following page.) Work on the assignment in your group. You will get a group grade for working together. Everyone works on the same problem together. In other words, do not go on until everyone in the group has done and understands the problem. Are they supposed to copy your work? Nooooooo! Help each other and explain how to do it. That’s what the grade is for. If you go on and leave the others, your personal grade for the day will be lowered. Finish for homework.
