Answer:

3: x = 6 and they are alternate interior angles.

4: x = 65 and they are alternate exterior angles.

5: x = I do not understand this question if you could please clarify it that would be amazing!

6: x = -13 and they are alternate interior angles

7: this one i am not understanding either if you could clarify this one that would be helpful as well.

Please prove or explain how to get AC, CM, & CP...<br><br> AC = 15<br> CM = 20<br> CP = 12

katovenus [111]

<h3>Explanation:</h3>

All of the right triangles are similar by AA similarity, so corresponding side lengths are proportional. The ratio of the long leg to the short leg is the same for the two smaller triangles, for example:

CP/AP = MP/CP

CP/9 = 16/CP . . . . . fill in the given numbers

CP² = 9·16 . . . . . . . multiply by 9·CP

CP = 3·4 = 12 . . . . . take the square root

Now, you can use the Pythagorean theorem to find AC and/or CM.

AC = √(9² +12²) = √225 = 15

CM = √(12² +16²) = √400 = 20

In summary, CP = 12, AC = 15, CM = 20.

_____

Once you have CM, you can see these are 3-4-5 right triangles, so you can determine the other lengths by using these side ratios.

3:4:5 = 9:12:15 = 12:16:20

_____

The altitude CP is called the "geometric mean" of AP and MP. It is the square root of their product. This is true for <em>any</em> right triangle, not just one with sides in the ratio 3:4:5. If you know this, you can write down your answers almost immediately. Above, we had to derive this fact using similarity.

What is the lateral surface area of a square pyramid with a side length 11.2 cm and a slant height 20 cm

madam [21]

Notice the picture below

the lateral area, or just the area of the sides, well, the sides are really just 4 triangles, so just get the area of each, and sum them up, that's the lateral area

The number of patients treated at Dr. McCormick’s dentist office each day was recorded for nine days. These are the data: 13, 16

NARA [144]

First, lets sort the list from smallest to greatest. This will help with median, mode, and range.

4, 6, 10, 12, 12, 13, 16, 16, 16

Next, lets find the mean. Mean is found by adding all numbers up, then dividing them by the number of entries in the data set.

$4+6+10+12+12+13+16+16+16 = 105$
$105 / 9 = 11.7$

So the mean is 11.7.

Next, we'll find the median. The median is the value in the center of the list. Because there are 9 values, that means the center of the list is 5 with four numbers on each side of it. The 5th number in the list is 12, so that's our median.

Continuing, the mode is the number or numbers that appears the most often. For this data set, 16 appears 3 times while all other numbers appear 2 times or less. So, the mode is 16.

Lastly, the range is the difference between the largest number and the smallest number.

$16 - 4 = 12$

So the range is 12.

The second answer in the list matches all of these values, and is the correct solution.
