Linear regression is a technique which consolidates a group of data points into a linear correlation considering the deviation of the points. In this case, we can manipulate the labels of x and y axis to create a linear correlation. The line is always dependent on the mean and the standard deviation so it is expected to pass through the mean,
Answer:

The constant of proportionality is 13
The value of x+y+z = 93
<u>Explanation:</u>
<u></u>
angle 1 = 18x
angle 2 = x+y
angle 3 = 30z
In rhombus, the diagonals intersect at 90°
Therefore,
angle 1 : 18x = 90
x = 90/18 = 5
angle 2: x+y = 90
5+y = 90
y = 85
angle 3: 30z = 90
z = 90/30 = 3
Value of x+y+z = 5+85+3 = 93
Thus, the value of x+y+z = 93
