Answer:
∠y=60°
Step-by-step explanation:
Question says to find the measure of the angle Y.
We have been given a picture of triangle XYZ. All angles are marked with same sign so that indicates that all three angles are equal.
∠x = ∠y = ∠z...(i)
We know that sum of all three angles of the triangle is always 180°.
So we can write:
∠x+∠y+∠z=180°
∠y+∠y+∠y=180° {using equation (i) }
3∠y=180°
divide both side by 3
∠y=60°
Hence final answer is the measure of angle y is 60 degree.
Answer: 0.064
Step-by-step explanation:
The formula to find the margin of error :-
Given : Significance level : 
Critical value : 
Sample size : n=400
The proportion of people support the candidate :p=0.44
Then , 
Hence, Margin of error = 0.064
