Answer:
<h2>x = 11°</h2>Step-by-step explanation:
From the question the total angle here is 90° that means the angles are complementary.
Complementary angles are angles that add up to 90°
To find the value of x add the individual angles that's ZWY and
XWY and equate it to
m XWZ that's 90°
So we have
ZWY +
XWY = m
XWZ
2x + 8 + 5x + 5 = 90
7x + 13 = 90
7x = 90 - 13
7x = 77
Divide both sides by 7
We have the final answer as
<h3>x = 11°</h3>Hope this helps you
The residual points include the difference between the value in Irwin's dataset and the predicted values
<h3>How to plot the residuals?</h3>The residual is calculated using:
Residual = Actual points - Predicted points
The actual points are:
(1,43), (3, 36), (5,22), (6, 25), (8,14)
The predicted points are:
(1,44), (3, 35), (5,26), (6, 22), (8,13)
Using the residual formula above, we have the residuals to be:
(x,y) = (1,-1), (3, 1), (5,-4), (6, 3), (8,1)
