What is 278 divied 2 by the long way

139

Step-by-step explanation:

278 divided by 2.

To do it in the long way I will have to split it since its on computer.

200 divided by 2 equal 100

70 divided by 2 equal 30 which is 60 so it is 70-60=10 then add the 8 and get 18

Then 18/2= 9

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

570, the answer is 570, hope it
