Answer:
C
Step-by-step explanation:
The sum of the angles is 90
2x + x = 90
3x = 90
x = 30
the angle ABC is 2x, so it means that is the double of x, so it is 60 degrees
The estimated standard error for the sample is 6
Given,
Sample size, n = 36
Sample variance,
= 1296
Standard deviation, s = √1296
= 36
Standard error, SE = 
= 
= 
= 6
