Answer:
C) 94
Explanation:
It is the same angle as the one that is measured to be 94°
Base angles in an isosceles triangle, assuming the base is the one that does not match any other side, are equal.
You are told one of them on the 1st triangle. 55º.
So you can assume the other one will also be 55º.
Internal angles in a triangle add up to 180º.
Subtract the sum of both angles (
) from 180 and you will get the third one (
).
This 70º angle is vertically opposite to one of the base angles of the other isosceles triangle. Knowing vertically opposite angles are equal, then the other angle must be also 70º.
Now you have one of the base angles for the second isosceles triangle!
Again, knowing that base angles in an isosceles triangle are equal,
must be equal to 70º.

Answer:
d) Conclude that the population mean annual consumption of beer and cider in Milwaukee is greater than 26.8 gallons and hence higher than throughout the United States.
Step-by-step explanation:
We have a hypothesis test about the true mean consumptionof beer and cider for U.S. 21+ years-old consumers with the following null and alternative hypothesis:
![H_0: \mu=26.8\\\\H_a:\mu> 26.8](https://tex.z-dn.net/?f=H_0%3A%20%5Cmu%3D26.8%5C%5C%5C%5CH_a%3A%5Cmu%3E%2026.8)
The result of the test is to reject the null hypothesis.
This means that there is evidence to support the claim that beer and cider consumption was higher than the national average in Milwaukee in 2017 .
If you draw a diagram of this, your given values of the resulting triangle give you the sides opposite and adjacent of the angle. The formula that uses these sides is tangent.
The tangent of an angle is equal to the ratio of the opposite side over the other non-hypotenuse side (adjacent).
Therefore;
![tan(40)=70/x](https://tex.z-dn.net/?f=tan%2840%29%3D70%2Fx)
![0.83909963117=70/x](https://tex.z-dn.net/?f=0.83909963117%3D70%2Fx)
![0.83909963117x=70](https://tex.z-dn.net/?f=0.83909963117x%3D70)
![x=70/0.83909963117](https://tex.z-dn.net/?f=x%3D70%2F0.83909963117)
![x=83.4227514823](https://tex.z-dn.net/?f=x%3D83.4227514823)
Where x is the length of the string in feet.
