Step-by-step explanation:
CDE = 2x, DEF = x
hexagon = 720°
720 = 115 + 145 + 160 + 90 + 2x + x
720 = 3x + 510
720 - 510 = 3x
210 = 3x
x = 210 ÷ 3
x = 70°
CDE = 2x
= 2(70)
= 140°
They each contributed $6.75. I got that because i divided the $27.00 by the 4 friends and got $6.75, to make sure I also multiplied the $6.75 by 4 and got $27.00
