Help me out please???

To answer this question you first have to find angle acb. You’ll take the sum of the triangle and plug it into an equation. 180=65+(4x+5). You combine like terms and then divide the 4 to both sides to get 27.5. Then you do the same thing to find bcd. 180=27.5+9x-5. Which is 17.1667. I hope that helps!
