You andyour partner will work together to solve these trigonometry related problems. You solve theproblems
Directions:
on the lefi andyour partner will solve the problems on the right. Whenyou are done,your answerswill match - but the
answers are NOT in the sqme order in both columns. Use vour calculator and round answersto the nearest tenth, unlessstated
otherwise. Good luck!
