Answer:
4*(7-2)2÷10
=4*5*1/5
=20/5
=4
Step-by-step explanation:
The sum of all exterior angles for every shape is 360 so just divide 360 by the measurement of one exterior angle (18) to get 20
The number was 160 because 5/4•128=160. 5/4 represents inverting 80% and multiplying it by the number to determine how the result became 128. For checking over all you have to do is do 4/5 or 80%•160 which shall give you 128.
