Betty's percentage is 15%.
The rate of change is the amount it changes for every missing assignment, therefore it would be -5.
Angle 4 is 144
180- angle 3 (36degrees) = 144 degrees
I think this is right
all you need to do is:
235-123= 112
then to make sure its correct you do:
123+112= 235
Hope this has helped you. :)
