Answer:
Step-by-step explanation:
Start with 180-38. That gives us 142. We know that 2 of the sides are the same so the two missing values are split evenly between 142. Angle 2 is 71.
71=x+84
subtract 84 from both sides
x=-13

2. How many skiers were at Telluride?
Correct answer choice is: 4500
Explanation:
As we can clearly see from the bar chart given that the y-axis represents the number of skiers in thousands and the Telluride bar reaches the halfway between number 4 and 5 on the y-axis, representing the number of skiers in thousands.

3. How many more skiers were at Vailthan at Keystone?
Correct answer choice is: 8500
Explanation:
As we can clearly see from the bar chart given that the y-axis represents the number of skiers in thousands and the Vail bar reaches the halfway between number 11 and 12 on the y-axis, and Keystone bar reaches the number 3 on the y-axis, and representing the number of skiers in thousands.
Therefore,
Vail = 11500
Keystone = 3000
Difference = 11500 - 3000
= 8500

4. How many skiers were at the fourmountains altogether?
Correct answer choice is: 28000
Explanation:
As we can clearly see from the bar chart given that the y-axis represents the number of skiers in thousands and the Vail bar reaches the halfway between number 11 and 12 on the y-axis, Aspen reaches at number 9, Telluride reaches between 4 and 5, and Keystone bar reaches the number 3 on the y-axis, and representing the number of skiers in thousands.
Hence,
Aspen = 9000
Telluride = 4500
Vail = 11500
Keystone = 3000
Total sum = 9000 + 4500 + 11500 + 3000
= 28000

5. What was the mean number of skiersat the four mountains?
Correct answer choice is: 7000
Explanation:
Mean can be find out by adding the all the number of skiers of each category and dividing the the total number f categories.
Hence,
Sum of skiers = 9000 + 4500 + 11500 + 3000 = 28000
Number of categories = 4
Mean = 28000 ÷ 4
= 7000

6. How many games did the Bears win?
Correct answer choice is: 25
Explanation:
As we can clearly see from the double bar graph given, the grey bar graph represents the number of wins whereas, the black bar graphs represents the number of loses. Hence, the bear's winning graph reaches to the number 25 on the games axis.

7. How many games did the Boars lose?
Correct answer choice is: 37
Explanation:
As we can clearly see from the double bar graph given, the grey bar graph represents the number of wins whereas, the black bar graphs represents the number of loses. Hence, the boar's losing graph reaches to the number between 35 and 40 but close to 35 on the games axis. So we can say that it is 37.

8. How many more games did the Hawks lose than win?
Correct answer choice is: 4
Explanation:
As we can clearly see from the double bar graph given, the grey bar graph represents the number of wins whereas, the black bar graphs represents the number of loses. Hawks win 4 games and loses 28 games. The difference can calculated as 28 - 4 = 4 games.

9. How many more games did theRats win than the Boars won?
Correct answer choice is: 19
Explanation:
From the given graph we can see that the rats won 32 games and the boars won 13 games.
Difference in winning is = 32 - 13 = 19 games
____________________________________________________________
10. Which team won twice as many games as it lost?
Correct answer choice is: Rats
Explanation:
Let's go through the bar graph and see the number of wins and number of loses.
Bears: Won 25; Lost 22
Boars: Won 13; Lost 37
Doves: Won 30; Lost 20
Hawks: Won 29; Lost 28
Rats: Won 32; Lost 16
So, Rats won twice the number of games to the number of games they lost.
____________________________________________________________
11. What fraction of its games did the Doves win?
Correct answer choice is: 3/5
Explanation:
Doves played a total of 30 + 20 = 50 games.
They won 30 games and lost 20 games.
Therefore,
We can say that they won 30 out of 50 games.
Rewriting their victories in fraction form;
30 / 50 = 6 / 10
= 3 / 5

Two similar triangles are never congruent. Similar triangles have the same shape, but their sizes may differ. They have corresponding angles that are equal and corresponding sides that are proportional to each other.
However, being similar does not guarantee that they are congruent.
Congruent triangles, on the other hand, have both the same shape and size. Their corresponding angles and sides are equal in length. Congruent triangles are essentially identical to each other.
In summary, similarity implies the same shape but different sizes, while congruence implies both the same shape and size. Therefore, two similar triangles are never congruent.

congruency means, exact twins, completely exact.
similarity means, they must look the same only, one can be larger or smaller than the other, the angles must be the same, but the lengths can be longer or shorter and that's ok.
if two figures are congruent, they are also similar, but if one is larger than the other, they're still similar, though not congruent anymore.
