Answer:
D 73º
Step-by-step explanation:
Total angles
a = (sides - 2) * 180
a = (5 - 2) * 180
a = 540
-------------------
Missing angle
x = 540 - (104 + 118 + 96 + 115)
x = 107
a is supplementary to x
m∠A = 180 - 107
m∠A = 73º
Answer:
b² ≈ 6.71
Step-by-step explanation:
The
= 6.708
6.708 ⇒ 6.71
and
≈ 45.0241
b² = 6.71
The size of Angle L should be the same as Angle C if the triangles are congruent (or at least similar) Since Angle C = 69o, then Angle L also = 69o. You should be very careful in accepting this assumption because looks can deceive. However if the assumption of congruency is not true, there is no way to solve the problem. L = 69o.
Answer: 0.0432
Step-by-step explanation:
Formula of Margin of Error :-

Given : Sample size : n= 400
The proportion of individuals use public transportation.=
Level of confidence = 0.95
Significance level : 
Critical value : 
Substitute the values in the given formula , we get

Hence, the margin of error for the confidence interval for the population proportion with a 95% confidence level. = 0.0432
