Answer:
23
Step-by-step explanation:
Every triangle adds up to 180 so we would add all of these expressions up and set them equal to 180. 13x-11+8x-9+30x-4=180. Simplify to 51x-24=180. Opposite operation with negative 24. 51x=204. Yet, again do the opposite operation to isolate x, 204/54, which leaves the answer of 4. But that is not the question. It is asking for angle W, well since we know what x is, we are able to plug in x to the expression used in angle W, 8(4)-9 which brings tha answer of 23 :)
