Answer:

A = 84º

B = 74º

C = 22º

Step-by-step explanation:

Since all the three angles of a triangle have to add up to be 180º, one can do...

A + B + C = 180º

So,

(4x+12) + (3x+20) + (x+4) = 180º

8x + 36 = 180º

8x = 144

x = 18

Then you just substitute x in each of the angles

A = 4(18) + 12 = 84º

B = 3(18) + 20 = 74º

C = (18) + 4 = 22º

***Math Check: 84 + 74 + 22 = 180º

Igoryamba

The correct answer is option (C) median.

The median will help Emily to find the number that appears in the middle of the 25 numbers that are arranged in ascending order.

<h3>What is the mean, median and mode? </h3>

The mean, median, and mode are the three most commonly used measures of central tendency for populations that do not have much data, that is, they do not need to be grouped.

The mean, also known as average, is the value obtained by dividing the sum of a cluster of numbers by the number of them.

When arranging the numbers from least to largest, the median sits exactly in the middle of the values that are above. The median is a set that is a value that is in the middle of the other values.

The number that appears most frequently in a set of numbers is called the mode.

So, The median will help Emily to find the number that appears in the middle of the 25 numbers that are arranged in ascending order.

Now that you have four, subtract 1

And you got 3
