Answer

Option A is correct.

Angle ABC = 110

Step-by-step explanation

The image isn't loading, but I can see the question and I have corrected it in the question tab.

From the image, we can see that Angle ABC is made up of Angle ABK and Angle KBC

Angle ABC = Angle ABK + Angle KBC

Angle ABC = 17x + 8

Angle ABK = 42

Angle KBC = 12x - 4

Angle ABC = Angle ABK + Angle KBC

17x + 8 = 42 + 12x - 4

17x - 12x = 42 - 4 - 8

5x = 30

Divide both sides by 5

(5x/5) = (30/5)

x = 6

Angle ABC = 17x + 8 = 17 (6) + 8 = 102 + 8 = 110

Hope this Helps!!!
