Answer:
<BOD = 120°
<EOC = 200°
<AOC = 135°
Step-by-step explanation:
Given:
<DOE = 115
°
<AOB = 60
°
<BOC = 75
°
<AOB + <BOD = 180°
so
<BOD = 180° - <AOB = 180° - 60° = 120°
<EOC = <EOA + <AOB + <BOC
As you know <EOA + <DOE = 180°
so
<EOA = 180° - <DOE = 180° - 115° = 65°
Now you find
<EOC = <AOE + <AOB + <BOC
<EOC = 65° + 60° + 75° = 200°
and
<AOC = <AOB + <BOC = 60° + 75° = 135°

(2/3)x^2 -6x + 15 = 0
Using the quadratic formula:
x = [-b +-sq root(b^2 - 4 *a*c)] / 2a
x= [--6 +-sq root(36 -4*(2/3)*15] / 2*(2/3)
x= [6 +-sq root 36 -40] / (4/3)
x1 = 4.5 + (2i / (4/3))
x1 = 4.5 + 1.5i
x2 = 4.5 - (2i / (4/3))
x2 = 4.5 - 1.5i
