First set up the equation (sum of the angles is 180)
2x + 2(x-1) + (5x +2) = 180
distribute:
2x + 2x -2 + 5x +2 = 180
combine like terms:
9x = 180
solve for x:
x = 20
SO:
2x° = 2(20) = 40 degrees
2(x-1)° = 2(20) - 2 = 40 - 2 = 38 degrees
5x + 2°= 5(20) + 2 = 100 + 2=102 degrees
check: 40 + 38 + 102 = 180

Answer: 3.75
Step-by-step explanation:
3.5/8=0.4375
when you round if last number is higher than 5 then you chose higher number, if it's lower, you chose lower. If it's 5, you look if next number is pair (chose higher) or nonpair (chose lower).
so you round to 0.437
and then 0.44
and then 0.4
