Answer:

ABD = 36

DBC = 54

Step-by-step explanation:

The three angles form a straight line so they add to 180

2x + 3x +90 = 180

Combine like terms

5x+90 =180

Subtract 90 from each side

5x+90-90=180-90

5x= 90

divide each side by 5

5x/5 = 90/5

x =18

ABD = 2x = 2*18 = 36

DBC = 3x = 3*18 =54
