Answer:
x=45
Step-by-step explanation:
Since AB is a straight line, it is 180 degrees
AOE + EOF + FOD + DOB = 180
15+x+2x+120-2x = 180
Combine like terms
135 +x = 180
Subtract 135 from each side
135-135 +x = 180 -135
x = 45
If they are three consecutive integers then they are:
k, k+1, and k+2 and the sum would then be:
s=k+k+1+k+2
s=3k+3
at least 4 different angles are present
