X = 8. You can find this by adding 90 (from the shown 90 angle to 18 and then subtracting 180-102 = 9x to since angle LJW is known to be 180 degrees (since its a straight line). Solving we get 72 = 9x.
Divide both sides by 9
X = 8
I hope this helps!

Answer:
5
Step-by-step explanation:
Given :
Observed values = 5, 10, 15
Expected freqencies = 10
χ² = Σ(observed - Expected)² / Expected
χ² = (5-10)²/10 + (10-10)²/10 + (15-10)²/10
χ² = 25/10 + 0/10 + 25/10
χ² = 2.5 + 0 + 2.5
χ² = 5
Answer:
The nation's total wealth more than doubled between 1920 and 1929, and this economic growth swept many Americans into an affluent but unfamiliar “consumer society.” People from coast to coast bought the same goods (thanks to nationwide advertising and the spread of chain stores), listened to the same music
