Answer:
88 degrees
Step-by-step explanation:
First add up all of your degrees
85+ 87+ 83+ 88+ 91+ 87+ 95= 616
Then divide that amount by the amount of different degrees you had in the question. You have 7 different degrees, so you will divide by 7.
616/7= 88
And boom you have your answer
29.6 + 14 = 43.6
43.6 - 14 = 29.6
Hope this helped!
