One bag would be 2.7 kg. If you equally pour 8 kg of oats into 3 bags, you divide 8 by 3 which gets you 2.666666666666667 (rounded to one decimal place is 2.7, it depends to what decimal place the question asks you to round your answer to).
Julie : 5.62
Micah : 5.62 x 5 = 28.1
Jermy : 5.62 + 6.72 = 12.34
The measure of angle 1 would be (3x+2) and the measure of angle 2 would be (5x+10). There is no way to determine the exact degrees of these angles because not enough information is given.
