Adding all vakus in data set and divide by the number of values in the data set

The mean is the average. You find it by adding all of the numbers in your set together, and then dividing that sum by the number of numbers that you have. For example, this is my set:

12   32    11    8    24

I would add those number together

12 + 32 + 11 + 8 + 24 = 87

Then I would divide 87 by the number of numbers I have, which, in the examples case is 5.

87 / 5 = 17.4

Answer: 42° and 138°
Steps: First find value of x by adding both equations and setting them equal to 180°:
3x + 12x - 30 = 180
15x - 30 = 180
15x = 210
x = 14

Next, put value of x into equations to find the angle:
3x
3(14)
42°

12x - 30
12(14) - 30
168 - 30
138°


11. Answer: 28°
Steps: Complementary angles add up to 90°, so subtract 62° from 90° to find its complementary angle.
90 - 62 = 28


12. Answer: Corresponding angles are congruent.

Write an algebraic equation based on the description. Two angles form a linear pair. The measure of one angle is 24° more than t
IgorC [24]
<h2><u>Answer:-</u></h2>

Given:

Two angles form a linear pair.

It means sum of their measures = 180°.

And,

Measure of one angle is 24° greater than the other.

Let the other angle be x.

→ First angle = (x + 24)

According to the question,

<h3>→ x + x + 24 = 180</h3>

→ 2x = 180 - 24

→ 2x = 156

→ x = 156/2

<h3>→ X = 78°</h3>

<u>There</u><u>fore</u><u>,</u>

  • 1st angle = 78°
  • 2nd angle = 78° + 24° = 102°
