Answer:
17
Step-by-step explanation:
Properties used:-
All sides of rhombus are equal therefore in the triangles
EQUAL SIDE OPPOSITE TO ANGLES, ANGLES BECOME EQUAL

Then we get,
3x-11=x+23
2x=34
x=17
Answer: 2.460
Step-by-step explanation:
The formula of Margin of Error for (n<30):-

Given : Sample size : n= 18
Level of confidence = 0.90
Significance level : 
Using the t-distribution table ,
Critical value : 
Standard deviation: 
Then, we have

Hence, the margin of error (ME) of the confidence interval with a 90% confidence level = 2.460
