Answer: 63°
<u>Step-by-step explanation:</u>
Since BD is the diameter, then arc BCD = 180°
Given that arc BC = 54°, then arc CD = 180° - 54° = 126°
∠DBC is an intercepted angle -> DBC = half of arc CD
![\angle DBC=\bigg(\dfrac{1}{2}\bigg)126^o\quad =\large\boxed{63^o}](https://tex.z-dn.net/?f=%5Cangle%20DBC%3D%5Cbigg%28%5Cdfrac%7B1%7D%7B2%7D%5Cbigg%29126%5Eo%5Cquad%20%3D%5Clarge%5Cboxed%7B63%5Eo%7D)
Answer:
5x -20
Step-by-step explanation:
p(x) = r(x) - c(x)
= 11x - (6x+20)
Distribute the minus sign
= 11x -6x -20
Combine like terms
= 5x -20
