Sometimes, the best way to answer a multiple-choice question is to see which choices are self-consistent.

__

Side lengths and their opposite angle measures in a triangle have the same ordering, least to greatest. It is informative to look at the answer choices with this in mind.

1a. C < A < B; a < c < b . . . . inconsistent

2a. C < A < B; c < a < b.

2b. C < A < B; c < a < b . . . . consistent

3a. B < A < C; c < a < b . . . . inconsistent

4a. B < A < C; a < c < b . . . . inconsistent

Only answer choice 2 is self-consistent. It is the correct one.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

here, we have,

from the given figure, we get,

The given triangle is a right angled triangle.

We need to find the value of x.

We know that cosx is adjacent side by hypotenuse.

Cos 37 = Adjacent side/ Hypotenuse

The value of cos37 degrees is 0.7654

0.7654 = x/15

15×0.7654=x

11.5 =x

12=x

Hence, The value of x in the given triangle is 12, Option C is correct.

What are the mean and the median?​

Answers

Answer: The Mean is 12 while the median is 10.

Step-by-step explanation: To find the mean we need to add all points scored which equals 108 points. Next, you will divide this by the number of players that scored points. Because there are 9 players we will follow 108/9=12. To find the median, you write out each number from smallest to largest or largest to smallest and find the number in the middle, this should act somewhat like an average however i would recommend using the mean to find an average. When writing out all the number they should look something like this: 6,7,7,7,10,11,13,23,24

Now that we have written them out, we find the middle most number which is 10 which means that our median is 10.

The mean is 12 points.

The median is 10 points.

Find an
equation for the line through (-6, 3) and
parallel to y = 3x + 1.

Answers

Since this line is parallel to y = 3x + 1 their slopes are equal. The slope is equal to 3. The line is also passing the point (-3,4).

This is the format of the line parallel to y = 3x + 1

y = 3x+ b

This line passes through point (-3, 4)

Replacing the values of y and x coming from the coordinates of (-3, 4)

4 = 3 * (-3) + b

Solving for the y-intercept b

4 = -9 + b

b = 4 + 9

b = 13

Knowing the slope as equal to 3 and the y-intercept as 13 the equation of the line is

y = 3x+13
