Answer:
Step-by-step explanation:
Knowing the measure of the <u>three angles</u><u> </u>can help us know if the triangle is acute, obtuse, right, isosceles, or equilateral and also compared with another we can tell if it is similar to another Δ.
Knowing the measures or the <u>three sides </u>of a triangle we can know if the triangle is right, isosceles, or equilateral and also compared with another we can tell if it is congruent or similar with another Δ.
We can see that knowing the sides will tell us more about the <u>congruency of triangles </u>whereas knowing just the angles can tell us that triangles are similar yet we will not know if the triangles are also congruent.

Answer:
The confidence interval for the unemployment rate is (0.056, 0.06) = (5.6%, 6%).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is:
The lower bound of the interval is:
The upper bound of the interval is:
In this problem, we have that:
So
The confidence interval for the unemployment rate is (0.056, 0.06) = (5.6%, 6%).
