Extra P./Geometry <br> Help quick! Thanks In Advance :)

The measure of angle C is 89 degrees.

<u>Step-by-step explanation:</u>

The given polygon ABCD is a quadrilateral.

<u>The property of a quadrilateral :</u>

The sum of the consecutive angles add to 180°.

In this quadrilateral, the angles B and C are consecutive angles. So, the sum of angle B and angle C is equal to 180 degree.

Given that,

  • The measure of angle B = 2x+3
  • The measure of angle C = 2x+1

<u>To find the value of x :</u>

m∠B + m∠C = 180

(2x+3) + (2x+1) = 180

4x + 4 = 180

4x = 180 - 4

4x = 176

x = 176/4

x = 44

<u>To find m∠C :</u>

m∠C = 2x + 1

⇒ 2(44)+1

⇒ 88+1

⇒ 89°

The measure of angle C is 89 degrees.

Mean measure of central tendency is the most affected by outliers. Then the correct option is B.

<h3>What is Mean?</h3>

The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.

Mean measure of central tendency is the most affected by outliers.

Then the correct option is B.
