<h3>What is the mean?</h3>

Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean.

Given

The data set is 14, 7, 2, 8, 3.

The mean of the data set is given by;

$\rm Mean = \dfrac{Sum \ of \ all \ data}{Number \ of \ data}\\\\Mean =\dfrac{14+7+2+8+3}{5}\\\\Mean = \dfrac{34}{5}\\\\Mean=6.8$

Find the measure of the angle that is 15x.

Naddika [18.5K]

15x would be the vertical angle of 16x -8 and since vertical angles are equal, then 15x = 16x -8.

15x = 16x -8
x = 8 and so the angle 15x = 15 * 8
which equals 120 degrees.
