Answer:

120

Step-by-step explanation:

ABC is a straight line so it is equal to 180

ABC = ABD + DBC

180 = 2x + x+90

Combine like terms

180 = 3x+90

Subtract 90 from each side

180-90 = 3x+90-90

90 = 3x

Divide each side by 3

90/3 = 3x/3

30 =x

We want to find DBC

DBC = x+90

= 30+90

= 120
