BD is the angle bisector of ABC. Find m ABC and m DBC. (Picture attached!) Thank you!!!

60 Degree,30 degree

Step-by-step explanation:

BD is bisector of ∠ABC

=> ∠ABD = ∠DBC

=> 3x = x + 20

=> 3x - x = 20

=> 2x = 20

=> x = 20/2  

=> x = 10

Now,

∠ABD = ∠DBC = x + 20 = 10 + 20 = 30 Degree

∠ABC = ∠ABD+∠DBC = 30+30 = 60 Degree

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
