When finding the median, do we have to put the numbers in order from least to greatest

There are usually multiple ways to solve any math problem.

You don't have to put the numbers in order if there's another way to find a value such that the number of numbers greater than that value is equal to the number of numbers less than that value.*

It is usually easiest to put the numbers in order, but it is not absolutely necessary.


* If the size of the set is odd, then the value found must be in the set. If the size of the set is even, the value found must be the average of the two numbers in the set that are nearest and either side of that value.

question 3.3 Angle 3

question 3.4   ABD and DBC are complementary angles

question 3.5   x is 7 degrees (first answer option)

Step-by-step explanation:

First question:

Recall that suplementary angles are those whose addition gives 180 degrees. Therefore the supplementary angle to angle 8 is angle 3.

Second question:

Recall that complementary angles are those angles which added give 90 degrees. Therefore, the only correct answer for this question is the third one: ABD and DBC are complementary angles.

Third question:

Notice that the two angles added should render 90 degrees, therefore, their expression should as well add to 90 degrees. Such can be written in equation form as:

( 6 x - 20 ) + (4 x + 40 ) = 90

combining like terms and later solving for x we get:

6 x + 4 x - 20 + 40 = 90

10 x + 20 = 90

10 x = 90 - 20

10 x = 70

x = 7

Therefore x is 7 degrees
