Answer:
Since ABD is a straight angle it is 180°
This means that the two expressions add to 180
8x - 41 + 9x + 17 = 180
Combine like terms
17x - 24 = 180
Add 24 to both sides
17x = 204
Divide both sides by 17
x = 12
Put x into the equation for <CBD
9(12) + 17 = CBD
108 + 17 = CBD
125 = CBD
The answer is 125°
Hope this helps!
